Sir but , kerosene has lesser density than water, it would flow on water but kerosene is optically denser than water, U have told it's because of density ( refractive index) in this video. Why kerosene is like this sir or is it a exceptional case ?
As you said denser medium could have higher refractive index . Sir apo oil is less denser than water but oil refractive index is higher than water , how ?
Brother, oil Oda density is lesser than water. But actually there is a thing called optical density, which is greater in oil than water. So light water ah vida oil la slow ah tha travel panum. Athan oil’s refractive index is greater than water’s refractive index. 😅
Dear sir when light travels from rarer to denser energy carried by the wave will A) decrease Or B) constant NCERT explanation is based on amplitude In that it is given.. " No. Energy carried by a wave depends on the amplitude of the wave, not on the speed of wave propagation" But if we take frequency related to energy it will give different option Pls clear ~rarer to denser Amplitude decrease so energy decrease (Or) ~Frequency constant so energy constant For this question energy is constant or decrease.

Nice sir give lot of videos for class 10..........I can understand this very easily
I am 8th but easy to understand 😀
You are great sir.This type of good tea hing I have never seen👍👍👍
Ungala mari oru physics sir enaku kedachirndha na physics la sure ah centum eduthirpen😍😁😇🥰
Such a nice way of teaching anna....thanks a lot ❤️😘
Super sir loved and completely understood ur lecture thank you soo much🙏
Thank u so much sir. Before i was getting confused in refractive index but now I am clear.once again thank you so much sir
Share our channel 😍
Ok
I can understand very easily
Thank u very much sir i easily understand the concept than in my online classes
Deivamey romba nandri
well explained.. Thank for your time.. Appreciate it
Nice vedio sir. Clear explanation tq so much 👍
Sir very very thank you sir because,I didn't go to the class when my teacher taught this lesson, thank you so much sir 💯💯👍👍💯💯💯
Sir tq so much I can understand very easily.....one kind request can u make videos for 12th cbse physics plzz sir
Sir neenga engaloda social sir maathiri ye sollitharinga thank you sir
superb teaching bro... Great work...
🙏 Nandri Anna. Super teaching
Super thank you sir I am finding for this kind of videos finally I got and I hope you upload many videos in 8th also sir..
Very nice sir .....you teaching was so good sir...
Sir thank u so much sir.
Your teaching skill is amazing sir
Sir thank you so much sir this video is very helpful for me
Really good teaching.
Thank you sir 🙏🙏👏
Thankyou.i was very helpful for my grade 10
Thank you sir
Anna I have one doubt, light travels always straight, then how light bends in refractive??? Please reply me Anna
Thank you sir it’s very useful
Good explanation sir
Super. very thanks
Super bro 👍 thank you

What a fantastic explain
Thank u sir. Very happy to see a educational channel in tamil.......unlike hindi......
Your handwriting is 👌
Very clear .thank u

Kandipa sir thankyou sir
sir you have said "v" is the speed of light in a particular medium. Is the value of "v" is same for all transparent surfaces?
Thank you sir
👌nice sir
Sir, why we should use sine function in snell's law. Why don't we use cosine or some other trigonometry function
Where does sin i and sin r come from? I understand that i=angle of incident and r=angle of refraction, but why say sin i and sin r
Super sir
Super SIR
Thank u pa muruga
Hi sir your teaching is semma
Super sir ✨
Vera level sir
Anna thank you so much
Thank u sir
Thanks na...
Lot of thank
Semma anna
Why we use sin angle in the snell's law instead of other trigonometric ratio sir🤔
We will solve the triangle created by normal and ray of light is opposite over hypotenuse
So will use sin ratio of opposite and hypotenuse
Super thala
Sir awesome explanation ..... 😀😀😀
Thank you 🙏

Thank you so much😍..but don't strain yourself..Take care of your health 🙏
Sir take care yourself😊
super sir
why do we use 'sine' in refractive index
Sir plzz about equation for refraction at single spherical surface at optics lesson
All posted
Super idhu enag sir eduthaaru but i can't understand it
sir intha videos cbse class use aaguma sir.
Crystal clear
Sir but , kerosene has lesser density than water, it would flow on water but kerosene is optically denser than water, U have told it's because of density ( refractive index) in this video. Why kerosene is like this sir or is it a exceptional case ?
Sir sin i/sin r =n1/n2 also we write sir
Transperency density
Nice
Please send videos for std 10 ( optics lesson)
Share our channel 😍
Iam saw this video at before public exam physics 2023
Sir give lot of videos for class 10 please sir
Sir why light speed slows down between two mediums
Medium changes
As you said denser medium could have higher refractive index . Sir apo oil is less denser than water but oil refractive index is higher than water , how ?
Brother, oil Oda density is lesser than water. But actually there is a thing called optical density, which is greater in oil than water. So light water ah vida oil la slow ah tha travel panum. Athan oil’s refractive index is greater than water’s refractive index. 😅
@@PurpleGalaxy998 but sir didn't tell that he simply used density, that's why I had a doubt on it
Sir in Space the speed of light
Sir whether this for 10th or 12th
Sir please make numericals
Please for class 10
Sir refraction and deviation onu thana?
Bending of rays..almost similar nu solla laam thaan
Sir dash and dash are two different media s

Nice

Anna ethukkaka sin i, sin r use pannurom (sin ,nu eppidi sollurom)
the angle is between opposite and hypotenuse of the triangle..so sin is used..
Sir reflection enga iruku?
Sir optic lesson yedunga sir pls pls pls

In snell's law How you take incident angle as sin i
Dear sir
when light travels from rarer to denser energy carried by the wave will
A) decrease
Or
B) constant
NCERT explanation is based on amplitude
In that it is given..
" No. Energy carried by a wave depends on the amplitude of the
wave, not on the speed of wave propagation"
But if we take frequency related to energy it will give different option
Pls clear
~rarer to denser
Amplitude decrease so energy decrease
(Or)
~Frequency constant so energy constant
For this question energy is constant or decrease.
Pls....
Who are watching this video in 2024 😂
DO NOT LEARN
