Vedclass · Answer

(B) According to Snell's Law, $n_1 \sin(i) = n_2 \sin(r)$, where $n_1$ and $n_2$ are the refractive indices of the two media, $i$ is the angle of incidence, and $r$ is the angle of refraction.Since the refractive index $n$ of a medium depends on the wavelength (or colour) of light (a phenomenon known as dispersion), $n$ varies for different colours.Specifically, for a given medium, the refractive index is higher for violet light and lower for red light.Therefore, for a constant angle of incidence $i$, the angle of refraction $r$ must vary to satisfy the equation $\sin(r) = \frac{n_1}{n_2} \sin(i)$.Thus, the angle of refraction is different for different colours.
