Light of wavelength `lambda` shines on a metal surface with intensity X and the metal emit Y electron per second of average energy Z what will happen to Y and Z if X is doubled ?

Y will be doubled and Z will become half

Y will remain same and Z will be doubled

Both Y and Z will be doubled

Y will be doubled but Z will be remain same

Text Solution

Verified by Experts

When intensity is doubled the number of electrons emitted per second is also doubled but the average energy of photoelectrons emitted remain the same
