alleryThe work function of a surface depends on the:
AMetal itself
BLight source
CRoom voltage
DWire length
Answer & Solution
Correct answer: A. Metal itself
1. Different metals release electrons with different ease.
2. The binding is a property of the material.
3. So the work function depends on the metal itself.
4. The answer is metal itself.
