Question

What is the wave length of light of frequency 5*10 14 Hz in the medium whose index of
refraction is 2.5 ? (c=3*10 8 m/s)

Answer 1

Answer:

8.5*10^5m

Explanation:

refractive index = c/v

By this we get,

v=1.2*10^8

We know that,

v=f* wavelength

By this we get,

wavelength = 8.5 * 10^ 5m

Answer 2
