What happens when a beam of light is shone at a block of glass with an angle of incidence of 90o?

• A.   The light will not refract because all parts of the wave front will change speed at the same time.
• B.   The light will refract because all parts of the wave front will change speed at the same time.
• C.   The light will not refract because the wave will not change speed.
• D.   The light will refract because the wave will slow down.
