Vedclass · Answer

(A, B, D) According to the experimental observations of the photoelectric effect:$1$. There is no significant time delay between the absorption of suitable radiation and the emission of electrons,even at very low intensities.$2$. Einstein's photoelectric equation is $K_{max} = h
u - \phi_0$,where $\phi_0$ is the work function. Electrons are emitted only if $
u > 
u_0$ (threshold frequency). Thus,no electrons are emitted below the threshold frequency.$3$. The maximum kinetic energy $K_{max}$ is a linear function of frequency $
u$,but it is not directly proportional to it (due to the work function term $\phi_0$).$4$. The maximum kinetic energy $K_{max}$ depends only on the frequency of incident radiation and the work function of the metal; it is independent of the intensity of the incident radiation.Therefore,statements $(a)$,$(b)$,and $(d)$ are correct.

Find the correct statement$(s)$ about the photoelectric effect.
