The splitting of white light into several colours on passing through a glass prism is due to

Explain the dispersion of white light.

Calculate the dispersive power for crown glass from the given data if $\mu_v = 1.5230$ and $\mu_r = 1.5145$.

Consider the four different cases of dispersion of a light ray which has all the wavelengths from ${\lambda _1}$ to ${\lambda _2}$ (where ${\lambda _1} > {\lambda _2}$). The dotted line represents the light ray of wavelength ${\lambda _{avg}}$. Which ray diagram shows the maximum dispersive power?

Which of the following curves gives the correct graphical representation between the refractive index $\mu$ of glass and the wavelength $\lambda$ of light?

For a medium,the refractive indices for violet,red,and yellow light are $1.62$,$1.52$,and $1.55$ respectively. Calculate the dispersive power of the medium.
