Explanation / Answer

Here,

a)

Its Wavelength increases because its speed increases

Frequency stays constant.

Air has a refractive index of about 1.0003
while glass varies about 1.5 .

b)

It decreases

the frequency is independent of the medium, it's the wavelength that changes

f = c/lmda

speed= c/(index of refraction)

c)

The index of refraction is equal to the speed of light in a vacuum divided by the speed of light in the medium. So it is an inversely proportional relationship: as the index decreases, the speed goes increases
