Which of the following statement is true?

Options

A. According to both Maxwell's electromagnetic theory and Huygens wave theory light is treated as a wave in nature and require medium to travel.
B. According to both Maxwell's electromagnetic theory and Huygens wave theory light treated as a particle in nature and require medium to travel.
C. According to both Maxwell's electromagnetic theory and Huygens wave theory light is treated as a wave in nature and does not require medium to travel.
D. According to Maxwell's electromagnetic theory light is treated as a wave in nature and require no medium to travel. According to Huygens theory light is treated as a wave in nature and require medium to travel.

Answer

To determine which statement is true regarding the nature of light according to Maxwell's electromagnetic theory and Huygens' wave theory, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Maxwell's Electromagnetic Theory:**
- Maxwell's theory describes light as an electromagnetic wave, which consists of oscillating electric and magnetic fields.
- Importantly, electromagnetic waves do not require a medium to propagate; they can travel through a vacuum.

2. **Understanding Huygens' Wave Theory:**
- Huygens' theory treats light as a wave and suggests that it requires a medium (like ether) to travel.
- However, this theory was later modified and is not consistent with our current understanding of light.

3. **Analyzing the Options:**
- **Option 1:** "According to both Maxwell's electromagnetic theory and Huygens' wave theory, light is treated as a wave in nature and requires a medium to travel."
- This is incorrect because Maxwell's theory states that light does not require a medium.

- **Option 2:** "According to both Maxwell's electromagnetic theory and Huygens' wave theory, light is treated as a particle in nature and requires a medium to travel."
- This is incorrect because both theories treat light as a wave, and Maxwell's theory does not require a medium.

- **Option 3:** "According to Maxwell's electromagnetic theory and Huygens' wave theory, light is treated as a wave in nature and does not require a medium to travel."
- This is partially correct for Maxwell's theory but incorrect for Huygens' theory, which does require a medium.

- **Option 4:** "According to Maxwell's electromagnetic theory, light is treated as a wave in nature and requires no medium to travel; according to Huygens' theory, light is treated as a wave in nature and requires a medium to travel."
- This option accurately describes both theories: Maxwell's theory states that light does not require a medium, while Huygens' theory suggests it does.

4. **Conclusion:**
- The correct statement is **Option 4**. It correctly reflects the nature of light according to both Maxwell's electromagnetic theory and Huygens' wave theory.
