Question

In a photocell, frequency of incident radiation is increased by keeping other factors constant (v > v₀), the stopping potential ______.

Options

• decreases

• increases

• becomes zero

• first decreases and then increase 

Answer 1

In a photocell, frequency of incident radiation is increased by keeping other factors constant (v > v₀), the stopping potential increases.

Explanation:

The stopping potential in a photocell is inversely proportional to the frequency of the incident radiation.
