hey dear its a wrong answer u can search in google or can ask ur teacher......the answer is frequency.....see the explanation u will understand
Frequency of light does not change on refraction , When a ray of light passes from one medium to another, its direction (or path) changes because of change in speed of light from one medium to another.
