Ma'am can you please clarify a small doubt that why T.I.R does not occures repeatedly inside the droplet rather occures just once or twice?
Why
@@mandakinisahu4313 , who says that it occurs for once or twice . It depends on angle of initial incidence . Also on multiple reflection the intensity reduces which may not support further reflection .
@@mandakinisahu4313 rainbow me TIR hota hi nhi hai rainbow me only reflection hota hai not the total internal reflection

My most favourite channel.I never feel disappointed after watching videos from this channel.😇❤Thanks a lot.
Manocha Academy is better
Mine too..don't memoriesis best
Yes exactly...😊
Who see this video by scan oswaal book's QR code 😂😂❤
I never find this video bro 😂
Same 😂😂😂
I think when all the seven colours emerges from the water droplets red color will come out first because it has the highest wavelength.. but you show violet coming first..
Yes its is violet coming first because of high frequency the speed of violet colour is high
@@akshayaaldrin709No, red comes out first.
@@akshayaaldrin709red color will come out first, it has higher wavelength and less frequency than violet
@@akshayaaldrin709 Red colour will be seen first due to scattering of light. Since red light has the highest frequency , it will not interact with the molecules present in the atmosphere, whereas blue light or violet has the least frequency so it will interact with maximum molecules of the atmosphere
Haven't you discussed about scattering of light like Tyndall effect, Colour of sun at sunrise and sunset??
No we dint discuss
You deserve more subs.
Maybe not
This is my favourite channel. It helps me so much in understanding all of these concepts. Thanks to you.
Perfect SUMMARIZATION of a long MIT Physics lecture on RAINBOW by Professor Walter Lewin. Awesome Teaching. Thank You for Posting it to all of the world.
Very well explained 👍🏻👌🏻👌🏻, it's so easy to understand by learning virtually 😇👌🏻👌🏻👍🏻, thanks a lot 🙏🏻 don't memorize channel ❤️.
My MR Sir taught us that in formation of rainbow there is no TIR there is refraction, internal reflection and refraction and this is also written in 12th NCERT physics
TIR and internal reflection are the same.....I'm pretty late to reply though xD
I think, this is most incredible channel i ever had....when i go through this for some concept clarity, it gives me immense clarity about my concern...i really appreciate this channel from the bottom of my heart. I would also like to thank the members of this channel who are doing hardwork to make it successful...Lots of love to this channel and keep up this Good works.💕💞👍👍
Our school makes us watch this channel and I love it sooooooooooooo much
Love this channel and watching ur videos from past 3 yrs
Hi Urmila, Thank you very much for your love and support. :)
Mam ur explanation style is amazing, great teaching..mam tqsm
Yes true !
what a great speaking style madam. I love this style.
What is a "speaking style"?
speaking method
I mean which method she take class or that topic to us
Hello! I just wanted to say that your videos is very helpful! They help me a lot with my Homework's especially during the Pandemic, it's helping me out so much! Your videos is also not only helpful, its also very entertaining me! It keeps my very motivated! Keep up the amazing and helpful work!
Hey! I have a query. If one light from each water droplet will reach us that means it depends on our position? So a person standing somewhere else will see a rainbow at some other place in the sky??Not very much distant but not exactly at the same place. Does it happen??
Rainbows are actually much larger than we can see because Infrared light and Ultraviolet light are also refracted. If you could see in these colors, the 2 outer bands will be huge (or there will be 2 NEW bands with totally different colors)
Thanks for making such amazing and informative videos, it really helps me being a class 10th student
It's my pleasure. We are really happy to hear that it was helpful and informative to you. We are glad that you understood the concept. You motivate us to do better. Keep watching our videos : )
@@InfinityLearn_NEETmam please explain about how the 🌍 earth form.
Your videos are really good. Concise and to the point.
I have my ip exam tomorrow i was not understanding thought i read but now I understood finally and can right own thank you
You are extremly superb.... explaining each n every point so clearly .... 👍👍👍👏👏👏 .. I really appreciate ur effort..
Thank you don't memorise you saved my time 🥰🥰🥰😊😊😊👍👍👍👍
Thank you explained very well. Plz upload videos for sign convention of lenses and mirror
Really its amazing video it helps Everyone to know about nature and simultaneously science
#BEST VIDEO for understanding rainbows🙆🙆🙆
Is total internal reflection or partial? Please, clarify I am in a dilemma
Thank u for helping students like me 😊 keep it up 😊
Thank u so much for your support and your explanation is always super duper awesome 🙂
Nicely explained .In the water droplet the space is formed by the different wavelength
I really like this channel ,it is appreciable. Thanks a lot for simplifying the topic 😀😀😀😀😀 keep it up
@@noushadrabbani5406 YOU ARE NOT THE CHANNEL
I want to know more about internal refraction
Mam, draw the normal at the point of refractions.
No
Chup
Really u r the best explainer in the world I have cleared my all the dought once again awesome keep it up 😘
Thanks thanks
Plz do a video about sign convention for lenses and mirrors 🙏🙏🙏before exam
Hi Devika, You will find all relevant lessons here- dontmemorise.com/course/view.php?id=199 :)
S... Even i want video in Cartesian plane and sign convention 😢😢
U make us understand v nicely,thnq so much
Ha welcome welcome

How u make this animation it's very beautiful 😍✨ .
Hardworking work u do
One of the best channel😍 to study.....
Thank you🙏 so much.....
Thank you for enLIGHTening me!
Great to know😇 this is how it happens... what is more interesting is why it happens...
Wow..... You are such a nice teacher.... before this video..I am totally confused
...but now fine
Please make a video on stress and strain.
Simply Superb
Thank u very much through this video i studied the whole chapter easily you would also upload more videos in science it would be helpful for all students anyway thanks🥰
One video on partial and total internal reflection
I really love don't memorise ❤
Brilliant. Thank you 😊
Ur voice is friendly. And I am watching ur channel from 3years only ur for study's and my brother love ur channel a lot. Tqqqq🙂🙂🙂 from deekshithathis is the best channelfor great explation and clearing doubts for all kids during corona once again tq so much and I love ur channel a lot keep doing video s and I wish u should have lot subscribe rs
Thank you so much Sagar for your appreciation. We are glad that you understood the concept. We are happy that we could help you learn. You motivate us to do better. We love our Pi Army and would like to stay connected. 🤗🤗
I have a question, I have captured three different full rainbows that have the same dimensions along with a double rainbow surrounding it but all three take in different locations some two years apart from the latest image. So how can the same rainbow keep occurring when the occurrence of capturing this I felt was a once in a lifetime occurrence?
How primary and secondary rainbows are formed?
Actually I didn't understood the topic of internal reflection
Me 2
then go through with physics wallah in his video you understand internal reflection
A ray of light when passing from a optically dense medium(water) to a optical rarer medium (air) at any angle of inclination tends to bend away from the perpendicular until the angle reaches a critical level in which the light becomes parallel to the refractive interface when this angle is increased the light reflects back into the same medium.
Can u plz make a video on tunning or LC circuit..and resonance??....... Plzz.
Mam can u plz upload a video based on carbon compound of state board syllabus
Please make a video on what is kinetic and potential energy
Interesting ...fascinating too
Thank you soooo much for clearing my concepts :))))))))
My favorite channel thank you so much ❤️
Excellent....No words 👌👌👌
Love u you help me a lot
plese describe about critical angle and total internal refraction. I hope you would so
Wow i understand very nicely
Such a beautiful video with animation 😍💕💕💕
I understand all thing 5his channel is very appreciable
I finally understand how rainbow reflected to my eyes, i thought theres an invisible layer in the atmosphere to reflect the light xD
Abbbaa enuff don't do show
You are doing a great job it cleared my all doubt
I tried making rainbow in my home
It actually works
Pls make a video on first order and second order rainbow...
I m begging you...pls
yeh hui naaa bat
majaaa
aaa gaya
Thank you ma'am for the great explanation ❤️❤️
You're most welcome Rohan. We are glad that you understood the concept. We are happy that we could help you learn. You motivate us to do better. Keep watching our videos : )
@@InfinityLearn_NEET don't do show
Thankyou so much mam for such a good explanation
I had the doubt which you solved at the last moment and which I was unable to understand from anywhere else.
Very good presentation
Thanks a lot mam😊
Ur exaplation is really amazing 👍
What an explanation 🔥🔥🔥🔥
Could you please upload this type of concept by diogrametically
Really Amaging & wonderful videos
Thank you, Gurukiran. Appreciations like these help us keep motivated😊
U r. Great mam.
Great explanation alongwith animated demonstration
Please make a lecture on working of electric motor
Thank u so much to this channel .....
AMAZING VIDEO...........!!LIKE ALL VISEOS!❤😍😎😎
i love u Don't Memorise
I saw many videos but I understood only by this video . 😊😊
I would like to understand more about rainbows forming in the opposite direction of the sun ...???
Please can u make a video on - why do rainbows have a curved shape
Deepchand garg they reflect off the curved firmament above us. Waterdrops are merely a surface for the rainbows to reflect upon no different than a lake or puddle allows us to see our reflection upon it. Only a large dome shaped prism can reflect a large dome shaped rainbow. We live in an enclosed ecosystem.
@@dav1djac0b In simple language plz
🙂
@@dav1djac0b First of all no thats a lie.
@@yoshikagekira6166 prove it.
Rainbows are actually full circles which are formed due to splitting and deviation of light from the spherical Sun or Moon.
Well explained I am impressed
Very helpful video...
very nice explanation
This is the best studying app and in this doubts can get clear properly
Thank you so much Anita 😀for your kind words. We are glad that you understood the concept. For more videos, please visit our website - dontmemorise.com/
Mam it is not the total internal reflection but only the internal reflection!
I enjoy your videos, you are just as useful as CorbettMaths
Thanks for making video
Thank you so much.
Happy Learning :)
U always explain clearly
It helped a lot❤️
Your channel is best that Byjus..👍👍👍
Nice Explanation
Students will understand
Good Animation 0:38
Helpful thanx
0:53 (CC) total internal reflection or Internal reflection only!???
NCERT book gives internal reflection only...(or this is imp to know bcz I have board)
First i clicked like then only i have seen the video!
Thankyou mam or sir for explaining detailed🙂🙂
Most welcome, p.s rao! keep watching😊
Superb mam tq a lot...❤
