Light Wave Speed Change

SATPHY-N9GZY9

Light from the air enters a transparent material which has an index of refraction of 2.0, which means that light travels half as fast in the material as it does in the air.

How do the wavelength and the frequency of the light in the material compare to the wavelength and the frequency of the light in air?

A
wavelength in material half of the wavelength in the air
frequency in material half of the frequency in the air
B
wavelength in material same as the wavelength in the air
frequency in material half of the frequency in the air
C
wavelength in material about 71% of the wavelength in the air
frequency in material about 71% of the frequency in the air
D
wavelength in material same as the wavelength in the air
frequency in material same as the frequency in the air
E
wavelength in material half of the wavelength in the air
frequency in material same as the frequency in the air
