Waves Inv 3 Review

If the angle of incidence is 50°, which statement is true? (Mark the one best answer.)

• The angle of reflection is 40°, because it is measured from the normal line, which is 90°.

• The angle of reflection is 50°, because it is equal to the angle of incidence.

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

• The angle of refraction is 50°, because it is equal to the angle of incidence.
