Question 429: Wave Optics

Question

A ray of light travelling in air have wavelength $\lambda $, frequency n, velocity v and intensity $I$. If this ray enters into water then these parameters are $\lambda $', n', v' and $I$' respectively. Which relation is correct from following ?

Accepted Answer

Frequency remains same.

Answer

$\lambda $ = $\lambda $'

Answer

n = n'

Answer

v = v'

Answer

$I$ = $I$'.
