Man this is so much better than that Unacademy . They always brag about killer visualisation but those are just some animations one Google search away. This is original intended to help us.

Great explanation! I find it's important to watch many videos on a topic.. Each one covers a different aspect of a subject and provides more info overall.. this one was perfect in that he showed howthe purpose of the main objective lens is to create an image within the focal length of the eyepiece and that acts as the magnifying lens... Excellent!

🛐I have seen no teacher like you before, I have learned from many in yt, but I can say proudly you are the best.

Sir, You're just amazing..
I also read few answers written by you on QUORA ( about angular wave number, entropy, fan rotation etc..)
And you're truly AWESOME...
