Who amongst the following used corpuscular theory to explain reflection and refraction of light?

Options

A. Newton
B. Maxwell
C. Young
D. Hertz

Explanation

To solve the question, "Who amongst the following used corpuscular theory to explain reflection and refraction of light?", we can follow these steps:

### Step 1: Identify the Scientists
We have four scientists mentioned:
1. Newton
2. Maxwell
3. Young
4. Hertz

### Step 2: Understand the Corpuscular Theory
The corpuscular theory of light was proposed by Isaac Newton. According to this theory, light is made up of tiny particles called "corpuscles." This theory was used to explain various optical phenomena, including reflection and refraction.

### Step 3: Analyze Each Scientist's Contribution
- **Newton**: Used the corpuscular theory to explain light behavior.
- **Maxwell**: Developed the wave theory of light and did not support the corpuscular theory.
- **Young**: Known for the wave theory and the double-slit experiment, not corpuscular theory.
- **Hertz**: Conducted experiments that supported electromagnetic wave theory, not corpuscular theory.

### Step 4: Conclusion
Based on the analysis, the scientist who used the corpuscular theory to explain reflection and refraction of light is **Newton**.

### Final Answer
**Newton** is the scientist who used the corpuscular theory to explain reflection and refraction of light.
