If the angle of incidence in the diagram is 50 degrees, which statement is true?

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

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

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

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