Prism

Find the ratio of the intensities of lights with wavelengths $500 \mathrm{nm}$ and $300 \mathrm{nm}$ which undergo Rayleigh scattering.

A beam of light consisting of red, green and blue is incident on a right-angled prism as shown in figure. The refractive index of the material of the prism for the above red, green and blue colours are $1.39, 1.44$ and $1.47$ respectively. What are the colours suffer total internal reflection?

What is dispersion? Obtain the equation for the dispersive power of a medium.

Derive the equation for the angle of deviation produced by a prism and thus obtain the equation for the refractive index of material of the prism
