CBSE IX Physics
How to find out the radius of curvature of a covex lens when focal length is given?
CBSE X Physics Light - Reflection and Refraction
what will happen to the focal length of a concave mirror, convex mirror, concave lens and convex lens when immersed in water? will it change ? if yes explain .(3 marks)
CBSE XII Science Physics Ray Optics and Optical Instruments
Q.On a convex lens ,light of red and violet colour is incident separately , then how does the focal length of lens change?
ICSE IX Physics Reflection of Light
the distance between a convex lens and a plane mirror is 10 cm.The parallel rays incidenton the convex lens after reflection from the mirror form an image at the optical centre of the lens.Find the focal length of the lens
CBSE X Physics
I got to knew that when light passes through the optical centre, then it bent , but as the lens is very thin , this bent is negligible and thus we neglect it but when other rays passes through the lens(except optical centre) then why does they bent more?lens is thin so why should'nt we neglect it too??
CBSE X Physics
When light travels in direction of optical centre of convex lens , it suffers very very slight deviation .....so from this, is it correct to conclude that such light rays/waves which are trevelling in direction of optical centre are actually travelling along the normal?explain

If the image formed in cinema is real then shouldn't it be inverted, and how do they avoid it?
