Vedclass · Answer

(C) Hard $X$-rays are characterized by their high energy and high frequency compared to soft $X$-rays. Since the energy of a photon is given by $E = h
u$,where $h$ is Planck's constant and $
u$ is the frequency,a higher energy implies a higher frequency. Also,since $\lambda = c/
u$,a higher frequency corresponds to a shorter wavelength. Therefore,hard $X$-rays have high frequency,high energy,and short wavelength.
