refraction of light

Question

Light travels from a region of fused quartz into a region of whale oil making an angle of incidence of 30 degrees. Which of the following best describes the path of the light as it moves into the fused quartz?

A) The light will bend toward the normal

B) The light will bend away from the normal

C)The light will continue without bending

D)The light will move in some manner not determined by the information here.

Answer 1

As we are not given the indices of refraction of either material we would have to assume answer D. That being said, if whale oil is like corn oil n=1.47 and quartz n=1.48, the answer could be c
