refraction watch

1. Say if light enters a more dense medium, refraction occurs. But what happens to the frequency, speed and wavelength of the light? I think wavelength changes, but not sure about the others.

The frequency is constant.
The phase velocity of the wave changes.

The phase velocity of the wave changes.
By v=f X lambda, velocity changing and frequency constant, wavelength also changes right?
Thanks

Wavelength decreases if entering a dense medium and increases if entering a less dense medium.

Congratulations to Harry and Meghan!

But did you bother to watch?

What do you actually do at University?
