$A$ charged particle oscillates about its mean equilibrium position with a frequency of $10^9 \; Hz$. What is the frequency of the electromagnetic waves produced by the oscillator?

The electromagnetic waves travel in free space with the velocity of

How are microwaves produced?

An electromagnetic wave with frequency $\omega$ and wavelength $\lambda$ travels in the $+y$ direction. Its magnetic field is along the $+x$ axis. The vector equation for the associated electric field (of amplitude $E_0$) is:

The speed of electromagnetic waves is the same for .......

$A$ plane electromagnetic wave is propagating along the direction $\frac{\hat{i}+\hat{j}}{\sqrt{2}},$ with its polarization along the direction $\hat{k}$. The correct form of the magnetic field of the wave would be (here $B_{0}$ is an appropriate constant)
