Name a prism required for obtaining a spectrum of Ultraviolet light.
How is the refractive index of a medium related to the speed of light in it?
A monochromatic ray of light passes from air to glass. The wavelength of light in air is λ, the speed of light in air is c and in glass is V. If the absolute refractive index of glass is 1.5, write down
- the relationship between c and V,
- the wavelength of light in glass.
A pond appears to be 2.7 m deep. If the refractive index of water is `4/3`, find the actual depth of the pond.
Light of a single colour is passed through a liquid having a piece of glass suspended in it. On changing the temperature of liquid, at a particular temperature, the glass piece is not seen.
Why is the light of a single colour used ?
State the relation between the refractive index μ and the velocity of light (vm) in that medium.
Why does the sun appear bigger during sunset or sunrise?
You are provided with a printed piece of paper. Using this paper how will you differentiate between a convex lens and a concave lens?
