Vedclass · Answer

(C) Hard $X$-rays are characterized by high frequency and low wavelength.The energy of an $X$-ray photon is given by $E = h
u = \frac{hc}{\lambda}$.Since hard $X$-rays have higher energy,they must have a shorter wavelength compared to soft $X$-rays.Among the given options,$0.1 \ \mathring{A}$ is the shortest wavelength,which corresponds to the hardest $X$-rays.

Which of the following wavelengths in $\mathring{A}$ represents 'hard' $X$-rays?
