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.
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🎉
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❤❤❤
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
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.

Soooo true

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

Home Work Question
A , V , M , O appears the same when viewed in plane mirror....
it indeed does cuz it is perfectly symmeterical💁💁🤦
You really teach nice🎉😊
A,V,M and O appear the same when viewed in a plane mirror.
thanks to this wonderful video I can understand this concept more easily. Thanks to you sir.
4:21 I think we are in FNAF 4
lol
Your teaching is very nice😊😊😊😊😊😊
Nice sir
Reflecting of mirror
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 😊😊😊😊

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
We are watching this video to learn chapter not the name of dish soaps like wim and many more.
bruh
Sir you teach very good 🎉🎉🎉🎉
Sir my exam is over
I have got first position in school
Thank you so much Sir ❤🤗👩🏻💻
Abo topperr😂😂😂
Congratulations 🎉🎉😊
Thanks sir! It helped me a lot...💜
You have exam tomorrow???
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🤞
@@Dragonn594 thnxxx
Can you explain glance angle of reflection
Sir tomorrow is my exam i have understand full chapter you are legand 💯💯💯💯💯💯💯💯🤘🤘🤘🤘🤘🤘
Instyn learning/ Instyn education is also good
Same 😅
Maths ma visualising solid shape PLEASE
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

What is reflection of light
Hi ma'am can you plz make one video on "our environment and natural resources"
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.
Thanks bro or sister for this explanation 😊🙏😍

Hiiii siiir thx so much I am going to 7th standard this video is very useful for me
AMAZING
Sir at 50:01 the mirror which you have drawn is Covex mirror not concave mirror
Thank you saurabh sir
40:00 is main point

A,V,M,O is the answer of your homework questions
We are learning chapter not the name of dish soap like wim and many more
Example and jokes kabhi sune hain?
You are right
Sir I have a doubt: Why does image appear upside down in concave mirror?
Because it is a mirror
Plane surface
Sir what is reflection of light
Bouncing back of light is known as reflection of light
Homework question ❓
It,s N
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
@@poojarathod5960 yes you are right
Sir A , V , M , O will be appear the same in a plane mirror
thanks sir for explaining so good you are the helping hand in exams thanks for this wonderful video

It was an amazing session, even though I'm in 6th I easily understood this concept.. Thank-you so much sir.
I am in 6th too, and I too understand this concept clearly
If you are in 6th what are you doing here kid😂😂🎉
im sure byjus is underpaying all these teachers
SIR, you are so amazing, your teaching is like ( NO WORDS ) all topics are clear now.

Wonderful session sir
WHY LIGHT ABSORB COLOUR
Light doesn't absorb colour the object absorbs colour and reflects rest so that we can see the object.
Answer of HomeWork Question - The letters A, V, M and O will appear same when seen In a plane mirror. 55:43
But sir,I have principal axis also in my book
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.

i not understand when w place close it is inverted or far it will erect
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
Thank you so much sir 💖💖
Homework answer= A, V, M, O are letters which appear same when viewed in a plane mirror
Light is a form of energy,which produces sensation to eye.(Is it corrext)
Light is a form of energy, which produces sensation of vision.
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.
this will help me a lot with my exams
😁
But you will fail in your exams 😂
😂😂
because we have plane mirror in home and it is lateral inverted
Perfect channel for education
Hi
some of the torch version have both it can make it wide and also
diminished how it can be possible
Sir your takla is best reflector of light than a mirror 🤣🤣🤣🤣😁😁😁😁😁👻👻👻👻
Ayyyo 💀
That is a bit rude
Your the waste fellow u rude fellow he is a teacher
This shows that in whole video you were watching sir head not listening and watching the main content of the video .
