When the frequency of light incident on a metallic plate is doubled, the K.E of the emitted photoelectrons will be
A
Doubled
B
Halved
C
Increase but more than double of the previous K.E.
D
Unchanged
Answer
Doubled
Explanation
Solution
Upon doubling the frequency, energy of photon will be doubled with work function of metal will remain constant. So K.E. of photon electron will be more than the double of what it possessed previously.
