Frequency is a property of the source.

Q. A ray of light travelling in air has wavelength $λ$ , frequency $n$ , velocity $v$ and intensity $I$ . If this ray enters into water then these parameters are $λ^{'}, n^{'}, v^{'}$ and $I^{'}$ respectively. Which relation is correct from following-

$λ = λ^{'}$

$n = n^{'}$

$v = v^{'}$

$I = I^{'}$

Q. A ray of light travelling in air has wavelength λ, frequency n, velocity v and intensity I. If this ray enters into water then these parameters are λ′,n′,v′ and I′ respectively. Which relation is correct from following-

λ=λ′

n=n′

v=v′

I=I′
