In a photoelectric emission, electrons are ejected from metals X and Y by light of frequency f. The potential difference V required to stop the electrons is measured for various frequencies. If Y has a greater work function than X, which graph illustrates the expected results.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
