Statement - 1 : When ultraviolet light is incident on a photocell , its stopping potential is `V_(0)` and the maximum kinetic energy of the photoelectrons is `K_(max)` when the ultraviolet light is replaces by X- rays both `V_(0) and K_(max)`increase
Statement - 2 : Photoelectrons are emitted with speeds ranging from zero to a maximum value became of the range of frequencies present in the incident light
