Assertion: The photoelectrons produced by a monochromatic light beam incident on a metal surface have a spread in their kinetic energies.
Reason: The work function of the metal is its characteristics property.
Reason: The work function of the metal is its characteristics property.
View answer and explanation
Correct option: B
Assertion is correct, reason is correct; reason is not a correct explanation for assertion
Option B is correct because the assertion is true (photoelectrons have a range of kinetic energies), the reason is true (work function is a material property), but the reason doesn't explain the assertion.
