Q

What is amplitude?

A
  • The maximum distance a point is being moved by a wave measured from it’s equilibrium position.
  • In simper terms, this is the wave’s height. This shows how much energy a wave has. If a sound wave has a higher amplitude, it is louder. If a light wave has a higher amplitude, it is brighter.

Q

What causes light to bend towards the normal?

A
  • The light wave is being transmitted through a medium of higher density, which causes it to slow down and refract towards the normal.

Q

What causes light to bend towards the normal?

A
  • The light wave is being transmitted through a medium of lower density, which causes it to speed up and refract away from the normal.
