Vedclass · Answer

(A) The photoelectric effect occurs when the frequency of incident radiation $v$ is greater than the threshold frequency $v_0$ of the metal. Ultraviolet $(UV)$ rays have a higher frequency than visible light and infrared rays. Infrared rays have a lower frequency than $UV$ rays,meaning $v_{IR} Since the photoelectric effect is triggered by $UV$ rays,the threshold frequency $v_0$ must be less than or equal to $v_{UV}$. Because $v_{IR} $X$-rays and $\gamma$-rays have frequencies much higher than $UV$ rays,so they will definitely cause the photoelectric effect.
