Q

What is refraction?

A

Refraction is the change in speed of a wave as it reaches a boundary between two media, resulting in a change in direction.

17
Q

What property of a wave is not changed by refraction?

A

The frequency

18
Q

When entering a denser material, light waves….

A

slow down and bend towards the normal.

19
Q

What is a ripple tank?

A

A shallow glass tank with an oscillating paddle/needle to create waves. It is illuminated from above so the waves can be seen on the surface below the tank.
