Question:
Statement-1 : When ultraviolet light is incident on a photocell, its stopping potential is $\mathrm{V}_{0}$ and the maximum kinetic energy of the photoelectrons is $\mathrm{K}_{\max }$. When the ultraviolet light is replaced by $\mathrm{X}$-rays, both $\mathrm{V}_{0}$ and $\mathrm{K}_{\max }$ increase.
Statement-2 : Photoelectrons are emitted with speeds ranging from zero to a maximum value because of the range of frequencies present in the incident light.
Correct Option: 1
Solution:
Speed of emitted electrons is independent of frequency of incident light, because for same frequency emitted electrons have energy from 0 to $\mathrm{KE}_{\max }$.
