### frequency of light

Why does the frequency of light remain constant when the light travels through different mediums even if the wavelength and speed change?

### Re: frequency of light

Frequency is equal to the ratio between the speed of light and wavelength, which stays the same.

Yes basically what the other guy said but in other words: The frequency stays the same because as a wave travels into a denser medium, it slows down and the wavelength decreases, so the proportion or ratio between the two is going to stay the same.
