Detailed Solution

KE = hv - W

W( work function ) is constant for given metal when frequency of incident radiation is doubled kinetic energy is more than doubled

Ex:- KE₁ = hv - W

KE₂ = 2hv - W

Thus Statement I is true

Statement II

Intensity of radiation $\propto$ Photo current.

Photo current is independent of frequency of radiation,

Thus Statement II is true
