Answer to Question #294171 in Optics for Chemistry

Question

A beam of light goes from one material into another. On physical grounds, explain why the wavelength changes but the frequency and period do not

Answer 1

Solution

Wavelength depends on refractive index.

When light enters from one medium to other, there is a change in refractive index. So, wavelength changes.

But frequecy and time period do not depend on medium so these doesn't change.
