Wave nature of electrons was experimentally verified by

Options

A. de broglie
B. hertz
C. einstein
D. davisson and germer

Answer

To solve the question regarding the experimental verification of the wave nature of electrons, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**: The wave nature of electrons is based on the de Broglie hypothesis, which suggests that particles such as electrons exhibit wave-like properties. This means that electrons can behave like waves under certain conditions.

2. **Identifying Key Experiments**: The most significant experiment that verified the wave nature of electrons was conducted by Clinton Davisson and Lester Germer in 1927. This experiment is often referred to as the Davisson-Germer experiment.

3. **Experimental Setup**: In the Davisson-Germer experiment, a beam of electrons was directed at a nickel crystal. The electrons were scattered off the crystal, and the angles of scattering were measured.

4. **Observations**: The results showed a diffraction pattern, which is characteristic of wave behavior. The observed diffraction pattern indicated that electrons were behaving like waves, confirming the de Broglie hypothesis.

5. **Conclusion**: Therefore, the wave nature of electrons was experimentally verified by the Davisson-Germer experiment, which demonstrated that electrons exhibit wave-like properties through diffraction.

### Final Answer:
The wave nature of electrons was experimentally verified by the Davisson-Germer experiment.
