n1 into a material with a higher index of
refraction n2 with an angle of incidence of 30.0°,
which of the following is true?
a. the angle of refraction is more than 30.0° and total internal
reflection may occur
b. total internal reflection may occur
c. the angle of refraction is more than 30.0°
d. the angle of refraction is less than 30.0° and total internal
reflection may occur
e. the angle of refraction is less than 30.0
