Question

The work function of platinum is twice that of calcium. If the minimum photon energy required to emit photoelectrons from the surface of platinum is E, then the minimum photon energy required for the surface of calcium would be:
Options
A 2E
B 3E/2
C E/2
Correct Answer
D Cannot be determined
Correct Answer

Option C is the correct answer.

Detailed Explanation

Minimum photon energy = work function. phi_Pt=2phi_Ca=E, so phi_Ca=E/2.

Hint

Minimum photon energy = work function.
