The wave character of moving electron was experimentally verified by :
(a)de-Broglie
(b)A-Einstein
(c)Garmer
(d)Schrodinger

Options

A. de-Broglie
B. A-Einstein
C. Garmer
D. Schrodinger

Answer

To solve the question regarding who experimentally verified the wave character of a moving electron, we can follow these steps:

### Step 1: Understand the Question
The question asks for the individual or group who experimentally verified the wave nature of electrons. This involves knowing about the experiments conducted in the field of quantum mechanics.

**Hint:** Look for key experiments related to the wave nature of electrons.

### Step 2: Recall Relevant Experiments
The wave nature of electrons was notably demonstrated through experiments that involved electron diffraction. The most famous experiment that verified this was conducted by Davisson and Germer.

**Hint:** Think about the historical context of quantum mechanics and who was involved in these experiments.

### Step 3: Analyze the Options
The options provided are:
- (a) de-Broglie
- (b) A-Einstein
- (c) Garmer
- (d) Schrodinger

While de-Broglie proposed the wave-particle duality concept, it was Davisson and Germer who experimentally verified it. The other names listed either contributed to the theory or were involved in different aspects of quantum mechanics.

**Hint:** Identify which of the names is associated with the experimental verification rather than theoretical contributions.

### Step 4: Identify the Correct Answer
Based on the historical experiments, the correct answer is (c) Garmer, as it refers to the experiment conducted by Davisson and Germer that confirmed the wave nature of electrons.

**Hint:** Focus on the experimental results rather than theoretical frameworks when determining the answer.

### Final Answer
The wave character of moving electrons was experimentally verified by (c) Garmer (referring to Davisson and Germer's experiment).
