Draw a graph showing the variation of stopping potential with frequency of the incident on a metal plate. How can the value of Planck's constant be determined from this graph?

Explanation

To solve the problem of drawing a graph showing the variation of stopping potential (V₀) with the frequency (ν) of incident radiation on a metal plate, and determining the value of Planck's constant (h) from this graph, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Photoelectric Effect**:
The photoelectric effect describes how electrons are emitted from a metal surface when it is exposed to light of sufficient frequency. The energy of the incident photons must be greater than the work function (φ₀) of the metal for electrons to be emitted.

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