The electromagnetic ($E$.$M$.) wave with the shortest wavelength among the following is:

The energy of a gamma $(\gamma)$ ray photon is $E_{\gamma}$, and that of an $X$-ray photon is $E_{X}$. If the visible light photon has an energy of $E_{v}$, then we can say that:

$A$ charged particle oscillates about its mean equilibrium position with a frequency of $10^9 \ Hz$. The electromagnetic waves produced:

The frequency order for $\gamma$-rays $(a)$,$X$-rays $(b)$,and $UV$-rays $(c)$ is given as:

Write the sources of visible rays and ultraviolet rays and their uses.

The correct order of electromagnetic waves with increasing frequency is
