The frequency (v) of the incident radiation is greater than threshold frequency `v_0` in photocell. How will the stopping potential very if frequency v is increased, keeping other factors constant.

Text Solution

Verified by Experts

As, `eV_0=h(v-v_0)`, therefore, the value of stopping potential `(V_0)` increases with the increase in frequency (v) of the incident radiation.
