Options

A. De Broglie
B. Devision and germer
C. G.P Thomson
D. Rutherford

Answer

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

### Step-by-Step Solution:

1. **Identify the Experiment**: The wave character of electrons was experimentally verified by the Davisson-Germer experiment.

2. **Understand the Background**: This experiment confirmed the de Broglie hypothesis, which proposed that particles such as electrons exhibit wave-like properties.

3. **Describe the Setup**: The setup of the Davisson-Germer experiment includes:
- An electron gun, which consists of a tungsten filament coated with barium oxide.
- A high voltage power supply that provides the necessary potential difference to accelerate the electrons emitted from the filament.

4. **Electron Emission and Acceleration**: When the tungsten filament is heated, it emits electrons. These electrons are accelerated to a specific velocity by the high voltage applied.

5. **Collimated Beam Formation**: The emitted electrons pass through a cylinder with fine holes, producing a collimated beam of electrons.

6. **Target Interaction**: This collimated beam of electrons is directed onto a nickel target. Upon hitting the nickel surface, the electrons scatter in various directions.

7. **Detection of Scattered Electrons**: The intensity of the scattered electron beam is measured using an electron detector connected to a sensitive galvanometer.

8. **Data Collection**: By moving the detector to different positions, the experimenters can measure the intensity of the scattered electrons at various angles, confirming the wave-like behavior through diffraction patterns.

9. **Conclusion**: The results of the experiment provided evidence for the wave nature of electrons, supporting the de Broglie hypothesis.

### Final Answer:
The wave character of the electron was experimentally verified by the **Davisson-Germer experiment**.
