Priyanka B Solutions for Chapter: Light : Reflection and Refraction, Exercise 3: Practice Problems-II

Calculate the speed of light in water. Given the refractive index of water is $\raisebox{1ex}{$4$}\!\left/ \!\raisebox{-1ex}{$3$}\right..$

The refractive index of diamond is $2.47$ and that of glass is $1.51$. How fast does light travel in glass as compared to diamond?

With respect to air the refractive index of ice is $1.31$ and that of rock-salt is $1.54$. Calculate the refractive index of rock-salt with respect to ice.

Refractive index of water is $\frac{4}{3}$ and for glass it is $\frac{3}{2}$, with respect to air. What is the refractive index of glass with respect to water?

A ray of light passes from air to glass. The angle of incidence is ${45}^{\circ }$. What is the angle of refraction, given the refractive index of glass is $1.5$.

A ray of light of frequency $5\times {10}^{14}$$\mathrm{Hz}$ is passed through a liquid. The wavelength of light is measured inside the liquid is found to be $450\times {10}^{-9} \mathrm{m}$. Calculate the refractive index of the liquid.

Monochromatic light of wavelength $589 \mathrm{nm}$ is incident from air on water. What is the wavelength, frequency and speed of refracted light? The refractive index of water is $\raisebox{1ex}{$4$}\!\left/ \!\raisebox{-1ex}{$3$}\right.$.
