The experimental evidence for dual nature of matter come from

Options

A. Plank's experiment
B. de Broglie's experiment
C. Devision and Germer'sexperiment
D. Ratherford's experiment

Answer

To solve the question regarding the experimental evidence for the dual nature of matter, we can follow these steps:

### Step 1: Understand the Concept of Dual Nature of Matter
The dual nature of matter refers to the idea that matter exhibits both particle-like and wave-like properties. This concept was proposed by Louis de Broglie, who suggested that particles such as electrons have wave characteristics.

**Hint:** Remember that the dual nature of matter is a fundamental concept in quantum mechanics, indicating that particles can behave as both particles and waves.

### Step 2: Identify Key Experiments
The most significant experimental evidence supporting the dual nature of matter comes from the Davisson-Germer experiment. This experiment demonstrated the wave-like behavior of electrons when they were scattered off a crystal.

**Hint:** Look for experiments that specifically involve the behavior of electrons or other particles demonstrating wave properties.

### Step 3: Analyze the Options Given
In the question, we have several options to choose from. We need to determine which option correctly identifies the experimental evidence for the dual nature of matter.

1. **First Option:** Incorrect
2. **Second Option:** Incorrect
3. **Third Option:** Davisson-Germer experiment - Correct
4. **Fourth Option:** Incorrect

**Hint:** Cross-reference the options with known experiments related to the dual nature of matter.

### Step 4: Conclusion
Based on the analysis, the correct answer is the third option, which refers to the Davisson-Germer experiment. This experiment provided clear evidence of the wave-like behavior of electrons, confirming de Broglie's hypothesis about the dual nature of matter.

**Final Answer:** The experimental evidence for the dual nature of matter comes from the Davisson-Germer experiment.
