Draw a plot showing the variation of photoelectric current with collector plate potential for two different frequencies, `v_1gtv_2` of incident radiation having the same intensity. In which case will the stopping potential be higher? Justify your answer.

Explanation

To solve the problem, we need to analyze the photoelectric effect and how the photoelectric current varies with the collector plate potential for two different frequencies of incident radiation.

### Step-by-Step Solution:

1. **Understanding the Photoelectric Effect**:
- The photoelectric effect occurs when light of sufficient frequency strikes a metal surface, causing the emission of electrons. The energy of the incident photons is given by \( E = h \nu \), where \( h \) is Planck's constant and \( \nu \) is the frequency of the incident light.

2. **Einstein's Photoelectric Equation**:
