Frequency

Vedclass · Answer

(B) When a light ray travels from one medium to another (e.g., from air to water), its frequency remains constant because it is determined by the source of the light. However, the velocity $(v)$ and wavelength $(\lambda)$ of the light change due to the change in the refractive index of the medium. The relationship is given by $v = f \lambda$, where $f$ is the frequency. Since $f$ is constant, the change in velocity results in a proportional change in wavelength.
