Vedclass · Answer

(C) The given equation for the electromagnetic wave is $E = E_0 \sin(kx - \omega t)$.Here,$k$ is the wave number,defined as $k = 2\pi / \lambda$,where $\lambda$ is the wavelength.$\omega$ is the angular frequency,defined as $\omega = 2\pi f$,where $f$ is the frequency.The speed of the wave in a vacuum is given by $c = \omega / k$.Since the wave is propagating in a vacuum,its speed $c$ is a constant $(c \approx 3 	imes 10^8 	ext{ m/s})$.Therefore,the ratio $k/\omega = 1/c$ is a constant and is independent of the wavelength $\lambda$.

An electromagnetic wave propagating in a vacuum is described by the equation $E = E_0 \sin(kx - \omega t)$. Which of the following is independent of the wavelength of the wave?
