Vedclass · Answer

(A) The correct option is $A$.When a ray of light is incident on a spherical surface such that it passes through the center $C$ of the sphere,the angle of incidence $i$ is $0^\circ$ because the ray is normal to the surface.According to Snell's law,$n_1 \sin(i) = n_2 \sin(r)$,which implies $\sin(r) = 0$,so the angle of refraction $r$ is also $0^\circ$.Since the ray passes through the center,it remains undeviated at both the entry and exit points of the spherical drop.Because there is no deviation or refraction at an angle,there is no dispersion of white light into its constituent colors.Therefore,the emergent light remains white and emerges without deviating.
