State the main implications of observations obtained from various photoelectric experiments. Can these implications be explained by wave nature of light? Justify your answer.

Explanation

### Step-by-Step Text Solution

1. **Introduction to Photoelectric Effect**: The photoelectric effect refers to the phenomenon where electrons are emitted from a material (usually a metal) when it is exposed to light of sufficient frequency. This effect was crucial in establishing the particle nature of light.

2. **Observations from Photoelectric Experiments**:
- **Photoelectric Current and Intensity**: It was observed that the photoelectric current is directly proportional to the intensity of light. This means that as the intensity of the incident light increases, the number of emitted electrons (and thus the current) also increases.
- **Stopping Potential**: The stopping potential (V) is the voltage needed to stop the emitted electrons from reaching the anode. It was found that the stopping potential is independent of the intensity of light. Instead, it depends on the frequency of the incident light.
- **Kinetic Energy of Emitted Electrons**: The kinetic energy (KE) of the emitted electrons can be expressed as KE = eV, where e is the charge of the electron and V is the stopping potential. This indicates that the energy of the emitted electrons is related to the frequency of the light rather than its intensity.
