What is reflection?

• Reflection is the bouncing of a wave off the surface that it strikes on.

• Reflection is the absorbing of a wave off the surface that it strikes on.

• Reflection is the bending of a wave off the surface that it strikes on.

• Reflection is the scattering of a wave off the surface that it strikes on.

When light passes at an angle to the normal from one material into another material in which its speed is higher 

• it is bent toward the normal.
• it always lies along the normal.
• it is unaffected.
• it is bent away from the normal.

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.
