Thanks

[@AwkwardAvii]

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 😭😭😭

Sir at 50:01 the mirror which you have drawn is Covex mirror not concave mirror

[@ThriftyToca]

I have a doubt if in convex lens if it is diminished then why are magnifying glasses showing so big?

[@mkgaming1171]

Because it is similar to concave mirror

[@aaliyajaiswk2596]

I think u got confused.... Convex MIRROR shows diminished image but Convex LENS shows enlarged image. Magnifying glass contains of CONVEX LENS.

[@LUV.1395]

Thanks sir! It helped me a lot...💜

[@k-pop_lover..78]

You have exam tomorrow???

[@poojarathod5960]

Sir I have a doubt that why the concave mirror forms inverted image and magnified or diminished

[@Soumyabhasin.117]

It forms the magnified image because of its properties

[@mayankchaudhary5929]

As it is formed like this and the purpose of this mirror is also like this

[@CheyaSceads]

we see an object when it reflects light, but then how can we see an irregular surface

[@aaratiyadav5656]

Does irregular surface does not reflect light?

[@iamlongname]

correct!@@aaratiyadav5656

[@Dragonn594]

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

[@Dragonn594]

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🤞

[@emaazfakhruddin6099]

Sir I have a doubt if convex lens show ur image small or diminished why in magnifying glass, the image shown is big ??

[@Invisible1195]

Convex lens and concave mirror are same so an concave can make both magnified and deminished

[@sawantmalik1328]

You can do both but by changing position

Sir can u explain the difference between reflection and refraction...?

[@Bruhhhhhh691]

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.

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

00:09 Summary of Class 7 Science Light Chapter in one shot 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

[@ajayakumarsahoo4341]

as we know we cannot see light ... then how u can say light is white????? 6:52

[@sitangsude-pq8fo]

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.
