Question

When read colour light moves from air to glass, how does the speed, wavelength and frequency of the

refracted ray compare with that for the incident ray?

a) speed decreases, wave length increases and frequency remains same

b) speed increases, wavelength decreases and frequency increases

c) Speed decrease, wavelength and frequency remains same

d) Speed decreases, wavelength decreases and frequency remains same​

Answer 1

Answer:

I think answer is a..

Explanation:

Because from rarer to denser speed will decrease, wavelength also increase so definitely frequency remains same..

I am giving answer as much as I know..
