Answer 1

ANSWER:

A

C

B

D

EXPLANATION:

Think of it this way: a light ray is just a piece of metal and the medium it travels through is just a magnetic field.

Consider the refractive index of the medium to be similar to the strength of the magnetic field.

Obviously, if you throw a piece of metal through a stronger magnetic field, it will travel slower.

Similarly, if a light ray passes into a medium with higher refractive index, it travels through the medium more slowly.

Hope this helped!
