Question

Why the frequency of light doesn't change during refraction?

Answer 1

Why does frequency of light does not changes during refraction ... As waves travel into the denser medium, they slow down and wavelength decreases. 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.

Answer 2

Answer:

here is your answer dear

Frequency doesn't change because it depends on travelling of waves across the interface. But speed and wavelength change as the material on the other side may be different, so now it might have a longer/shorter size of wave and so the number of waves per unit time changes
