Light Waves Investigation

Which labeling is correct?

• A = angle of incidence, B = normal line,

  C = angle of reflection

• A = angle of reflection, B = normal line,

  C = angle of incidence

• A = angle of incidence, B = angle of reflection,

  C = normal line

• A = angle of incidence, B = normal line,

  C = angle of refraction

If the angle of incidence in the diagram above is 60°, which statement is true?

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

• The angle of reflection is 60°, because it is equal to the angle of incidence

• The angle of refraction is 70°, because it is greater than the angle of incidence.

• The angle of refraction is 60°, because it is equal to the angle of incidence.
