Vedclass · Answer

(A) The deviation $\delta$ produced by a prism is given by the relation $\delta = (\mu - 1)A$, where $\mu$ is the refractive index of the material of the prism and $A$ is the angle of the prism.According to Cauchy's formula, the refractive index $\mu$ is inversely proportional to the square of the wavelength $\lambda$ $(\mu \propto \frac{1}{\lambda^2})$.Since the wavelength of red light is the longest among the visible spectrum, it experiences the least refractive index $\mu$.Consequently, red light undergoes the minimum deviation $\delta$ compared to other colours.

When white light is passed through a prism, which colour shows the minimum deviation?

Minimum deviation is observed with a prism having angle of prism $A$,angle of deviation $\delta$,angle of incidence $i$,and angle of emergence $e$. We then have generally

$A$ prism has a refracting angle of $30^\circ$ and a refractive index of $\sqrt{2}$. One of its faces is silvered. At what angle of incidence $i$ should a ray be incident on the other face so that it retraces its path after reflection from the silvered face?

On which factors does the angle of deviation produced by a prism depend?
