Reflection, refraction, and color

If the angle of incidence in the diagram above is 40°, which statement is true?

• The angle of reflection is 30°, because it is measure from the normal line, which is 90°.

• The angle of reflection is 40°, because it is equal to the angle of incidence.

• The angle of reflection is 60°, because it is greater than the angle of incidence.

• The angle of refraction is 40°, because it is equal to the angle of incidence.
