[@loligosq1946]

sir please make sound clearity we can't hear properly

[@himanithakur7528]

mind blowing sir

[@sridhardutta9434]

Sir, in 3:20 u said that the ray can even move straight acc. to the incident ray in certain conditions. What are those conditions sir? I am confused....

[@Pravinmishra1990]

Sridhar Dutta ji when refractive index will be 1,ie. the refractiv index of both medium is equal then the ray will travel in streight line...

[@kashish291_0]

Either they have same refractive index or the incident ray strikes normally at the interface of the 2 medium

[@arunjindal9369]

Sir what is difference between optical centre and geometrical centre

[@idreesk7752]

sir thnks u sooooooooooooooooooooo much I love u .......mujhe just ap he se physics ki samj ate hy. ....

[@nikhil4510]

sir, is their any physical quantity whose refractive index is less than 1 ??

[@vipulgautam6633]

No there is no such quantity

[@holylightacademy8761]

thanks sir. You are doing great job

[@aishwaryarai4174]
