प्रश्न
When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency.

उत्तर
Frequency and wavelength of light are related as
`v=v/lambda`
where v is the velocity of light. As the wave travels from one medium to another, the wavelength of light changes changing the speed of light with it. The frequency remains constant.
