The frequency and intensity of a light source are both doubled. Consider the following statements
A. The saturation photocurrent remains almost the same
B. The maximum kinetic energy of the photoelectrons is double

Options

A. Both `(i)` and `(ii)` are true
B. `(i)` is true but `(ii)` is false
C. `(i)` is false but `(ii)` is true
D. Both `(i)` and `(ii)` are false

Answer

B

Explanation

`I=(nhv)/(tA)`, when frequency is doubled for `I` to become doubled `n` should remain the same. `therefore` saturation photo current remains the same but maximum kinetic energy becomes more than doubled (from `KE_(max)=hv-w`)
