Statement $A$ is false, but $B$ is true.

Vedclass · Answer

(D) Statement $A$ is false because in photovoltaic cells, the generated photoelectric current is directly proportional to the intensity of the incident light.Statement $B$ is true because, according to Einstein's photoelectric equation, $K_{max} = h
u - \Phi_0 = \frac{hc}{\lambda} - \Phi_0$. Since the maximum kinetic energy $K_{max} = \frac{1}{2}mv^2$ depends on the frequency or wavelength of the incident light, the velocity $v$ of the photoelectrons also depends on the wavelength $\lambda$ of the incident radiation.Therefore, $A$ is false and $B$ is true.

Consider the two following statements $A$ and $B$ and identify the correct choice given in the answers:
