Question

Explain why the frequency of light does not change as it travels from one medium to another medium?

Answer 1

Answer:

Wave speed, frequency and wavelength in refraction

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Answer 2

Answer:

Frequency is a defining feature of the ray.when light travels from one medium to another the change in speed is compensated by the change in wavelength and making the frequency constant

Speed = wavelength *Frequency
