उत्तर
Given: aμg = `3/2`
gμa = `1/(""_"a"mu_"g")`
= `1/(3//2)`
= `2/3`
= 0.67.

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.

Draw ray of light bending towards the normal while passing from glass to water. Label your diagrams.
The diagram shows the path of a ray of light through a rectangular glass block placed in a liquid of uniform density.
What should be the rate of the speed of light through the liquid to the speed through the glass so that there is no refraction of light at the boundaries of the glass block when the system is illuminated by the light of one colour?
