A student uses a ray box to shine a ray of light at a plane mirror and then at a rectangular glass block.
State the law of reflection.
The ray meets the mirror with an angle of incidence of 35∘35^{\circ}35∘.
Give the angle of reflection.
State what is meant by the normal.
Give the name of the process in which light changes direction as it passes from air into glass.
The student shines the ray into the glass block along the normal.
Describe what happens to the direction of the ray as it enters the glass.
