refraction

Refraction

The Change in direction of a wave as it passes from one medium to another and is caused by its change in speed

How does light travel in a more dense material

Slowly

Which way will light bend when travelling from a less dense material to a more dense material

Towards normal

What can be said about the frequency of a wave when it travels through a more dense medium and the wave speed decreases

Frequency stays the same

What can be said about wavelength of a wave when it travels through a more dense medium and the wave speed decreases

Wavelength decreases
