Monochromatic light of wvalength `589 nm` is incident from air on a water surface. What are the wavelength, frequency and speed of (a) reflected and (b) refracted light ? `mu` of water is 1.33`.

Options

A. 589 nm
B. 443 nm
C. 333 nm
D. 221 nm

Answer

B

Explanation

Since, `lambda prop (1)/(n) `
`rArr " " lambda (" in water") = (589)/(1.33) = 443` nm.
