An electromagnetic wave going through vacuum is described by
` E= E_0 sin(kx- omega t)`. Which of the following is/are independent of the wavelength?

Options

A. k
B. `omega`
C. `k//omega`
D. `komega`

Answer

C

Explanation

The angular wave number `k=(2pi)/(lambda),` where `lambda` is the wave length. The angular frequency is `omega=2piv`.
The ratio `(k)/(omega)=(2pi//lambda)/(2piv)=(1)/(vlambda)=(1)/(c )="constant"`
