mid-night studying experience can make u feel so dumb sometimes. Right now im 24 minutes in the video and i literally got shocked when sir said "u will get this in more detail in class 10th, and even 8th. but for now, because u guys r in class 7th..." i hurried to check the title and legit felt so dumb because im a class 8th student 😭😭😭
So actually when light strikes on an irregular surface it reflects back in different direction which make us help see the texture and shape of the object
And actually every object reflect light but when light strikes at a plane or polished surface all the light rays moves in a same direction so we can see ourselves but when light falls on a irregular surface we cant see ourselves but we can see it hope it helps🤞
Reflection:- when a light gets bounces back from an shiny object which is polished from another side. ex:-A ray of light got reflected from mirror. Refraction:- when a light passes a transparent object. ex:- a ray of light passes the top of ocean.

The light coming from lamps or led tubes mostly looks white to our eyes. Sir said that before explaining the prism part that it breaks white colour into 7 colours. The glowing light that is emited is often considered as white to our eyes.
Homework question: Which of the following letters A,V,M,N,P,O,R appear same when viewed in a plane mirror? Answer: These letters appear same in a plane mirror - A,V,M,O The session was really amazing sir❤❤❤
Thank u sir it's my exam time But the lens part was not understood But u have put on a lot effort in explaining. All the other concept are clear. It was very much helpful for revision once again thank you Hope you work on the lens part Thank you🎉
they have a better english speaking skill than you, it might be a little typing mistake, because there are many comments and while replying to many, they might get mistakes?? everyone makes mistakes. even you do. so it isnt such a big deal.@@OMPrakash-pt7ze
Sir Apne bola ki convex mirror toh rear view mirrors m hota h toh sir vo for diminished image kaise form karega kyki rear view mirrors toh sab bada dikhane h na uspe bola bhi tha Apne . Please explain me❤

I have a doubt if in convex lens if it is diminished then why are magnifying glasses showing so big?
Because it is similar to concave mirror
I think u got confused.... Convex MIRROR shows diminished image but Convex LENS shows enlarged image. Magnifying glass contains of CONVEX LENS.
32:38 khana to mast aya hai or tasty bhi hai 😊😊🎉
Bhai muje bhi Dede😂😂😂😂😂😂
You really teach nice🎉😊
Sir I have a doubt that why the concave mirror forms inverted image and magnified or diminished
It forms the magnified image because of its properties
As it is formed like this and the purpose of this mirror is also like this
Thanks sir for this wonderful amazing video 😊😊😊😊
Sir my exam is over
I have got first position in school
Thank you so much Sir ❤🤗👩🏻💻
Abo topperr😂😂😂
Congratulations 🎉🎉😊
we see an object when it reflects light, but then how can we see an irregular surface
Does irregular surface does not reflect light?
correct!@@aaratiyadav5656
So actually when light strikes on an irregular surface it reflects back in different direction which make us help see the texture and shape of the object
And actually every object reflect light but when light strikes at a plane or polished surface all the light rays moves in a same direction so we can see ourselves but when light falls on a irregular surface we cant see ourselves but we can see it hope it helps🤞

Sir you teach very good 🎉🎉🎉🎉
Sir at 50:01 the mirror which you have drawn is Covex mirror not concave mirror
thanks to this wonderful video I can understand this concept more easily. Thanks to you sir.
Miracle 10:41 10:45 10:48
Sir I have a doubt if convex lens show ur image small or diminished why in magnifying glass, the image shown is big ??
Convex lens and concave mirror are same so an concave can make both magnified and deminished
You can do both but by changing position
Thanks sir! It helped me a lot...💜
You have exam tomorrow???
Reflecting of mirror
Nice sir
33:04 like sir's head chikna takla tvs-takla very smart

Home Work Question
A , V , M , O appears the same when viewed in plane mirror....
it indeed does cuz it is perfectly symmeterical💁💁🤦
Can you explain glance angle of reflection
Sir I had not understand properly the difference between concave and convex mirror .😮😮😮
Sir I have subscribed you from 4 devic
Normal means : perpendicular to mirror surface
Yes

Sir can u explain the difference between reflection and refraction...?
Reflection:- when a light gets bounces back from an shiny object which is polished from another side. ex:-A ray of light got reflected from mirror.
Refraction:- when a light passes a transparent object. ex:- a ray of light passes the top of ocean.

02:46 Light is energy and enables us to see things
07:53 Reflection of light is the bouncing back of light from a surface.
10:14 Reflection is the process of light bouncing off different surfaces.
15:34 The law of reflection states that the incident angle is equal to the reflected angle.
17:58 Real images can be obtained on a screen.
22:34 Reflected rays of light appear to meet when extended backward
24:58 Real and virtual images have distinct properties
29:12 Size of object is equal to size of image in a plane mirror
31:38 Understanding image formation in plane mirrors and observations related to image size
36:35 Concave mirrors can form real and inverted images on a screen and inside the mirror.
39:01 Concave mirror can form erect and magnified images
43:48 Concave mirror can form virtual, erect, and magnified images.
46:23 Focus of concave mirror and convex lens
51:21 Convex lens can form both real and virtual images.
53:35 Prism splits white light into seven colors
57:27 Understanding the difference between erect and inverted images
59:44 The importance of taking care
Sir I have a doubt: Why does image appear upside down in concave mirror?
Because it is a mirror
4:22 It looks like horror game because it belongs to a horror game 💀 (five nights at freddy's 4)
Homework question ❓
Letter O is going to appear same when viewed in a plane mirror .

as we know we cannot see light ... then how u can say light is white????? 6:52
The light coming from lamps or led tubes mostly looks white to our eyes. Sir said that before explaining the prism part that it breaks white colour into 7 colours. The glowing light that is emited is often considered as white to our eyes.
I don't know why but this video was not that good It didn't clear my concept😥
No it’s not was a amazing session 😊
Same
You mad

Sir I want to ask u one question that how can we change the path of light
With placing an opaque object between the path of light
We will not change the path of light it will be straight only but if we put opaque material in the path of light it will form shadow

because we have plane mirror in home and it is lateral inverted
Homework answer= A, V, M, O are letters which appear same when viewed in a plane mirror
11:40 because of shiny surface
A,V,M and O appear same because they cannot be laterally inverted on a plane mirror
By Pavan
They are latterally inverted but it looks the same

THIS CHAPTER IS SO HARDDDDDD WTHHH
Fr like wtf is an convex mirror , lens and whatever 👾
It's long but not hard
If you will not focus on a thing it will become harder
Sir Apne bola ki convex mirror toh rear view mirrors m hota h toh sir vo for diminished image kaise form karega kyki rear view mirrors toh sab bada dikhane h na uspe bola bhi tha Apne . Please explain me❤

sir First you told concave has real and virtual image at 42:22 min and next time you told at 51:48 it's convex what is actually right !?
U don't have brains or what... it's Concave mirror and Convex lens😂😂
Sir convex and concave shorts link
im sure byjus is underpaying all these teachers
