Question

For a glass prism, the angle of minimum deviation will be smallest for the light of

✓

Answer

(d) red colour.
Explanation: For a glass prism, the angle of minimum deviation will be smallest for the light of red color. As wavelength of red color is maximum among all, hence, $\mu \propto \frac{1}{\lambda}$, hence $\mu$ is smaller. As $\mu$ decreases, angle of deviation decreases.
