State the speed of light in (a) air, (b) water, and (c) glass.
A light ray passes from water to (i) air, and (ii) glass. In each case, state how does the speed of light change.
The speed of light is maximum in (a) glass (b) water (c) air (d) wood
(a) State the laws of refraction of light. Give an expression to relate the absolute refractive index of a medium with speed of light in vacuum. (b) The refractive indices of water and glass with respect to air are 43 and 32 respectively. If the speed of light in glass is 2×108 ms−1, find the speed of light in (i) air, (ii) water
A monochromatic beam of light passes from air into a glass block.
An expression that relates the wavelength of light, with the speed of light in air and the speed of light in glass is:
