Explain Briefly how classical theory could not explain the phenomenon of photoelectric effect

Explanation

### Step-by-Step Solution

1. **Introduction to Classical Theory**:
- The classical theory of light, primarily the wave theory, posits that light behaves as a wave and that energy is distributed continuously over the wavefront.

2. **Absorption of Energy**:
- According to the wave theory, when light waves strike a metal surface, the free electrons present at the surface absorb energy continuously from the incoming light waves.
