This diagram illustrates that...

• more dense media cause light to get slower and bend towards the normal.

• more dense media cause light to get faster and bend towards the normal.

• more dense media cause light to get slower and bend away from the normal.

• more dense media cause light to get faster and bend away from the normal.
