A clear transparent glass sphere `(mu=1.5)` of radius R is immersed in a liquid of refractive index 1.25. A parallel beam of light incident on it will converge to a point. The distance of this point from the center will be

If a small angled prism, made of glass is immersed in a liquid of refractive index 1 and a ray of light is made incident on it, then

A lens is made of flint glass(refractive index=1.5).When the lens is immersed in a liquid of refractive index 1.25 ,the focal length

A lens is made of flint glass (refractive index =1.5 ). When the lens is immersed in a liquid of refractive index 1.25 , the focal length:

A lens is made of flint glass (refractive index =1.5 ). When the lens is immersed in a liquid of refractive index 1.25 , the focal length:

Refractive index of the material of concave lens is mu . The lens is immersed inb a medium of refractive index mu_(1)(mu_(1)gtmu) . A parallel beam of light is incident on the lens. Draw a diagram to show the path of emergent rays.
