Assertion : Electromagnetic waves are transverse in nature
Reason : The electric and magnetic fields in electromagnetic waves are perpendicular to each other and to the direction of propagation.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Explanation

To solve the assertion and reason question regarding electromagnetic waves, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Electromagnetic waves are transverse in nature."
- A transverse wave is defined as a wave in which the oscillations of the medium are perpendicular to the direction of wave propagation.

2. **Understanding the Reason**:
- The reason states that "The electric and magnetic fields in electromagnetic waves are perpendicular to each other and to the direction of propagation."
- In electromagnetic waves, the electric field (E) and the magnetic field (B) oscillate in planes that are perpendicular to each other and also perpendicular to the direction in which the wave is traveling.

3. **Visualizing the Concept**:
- To visualize this, imagine a wave propagating in the x-direction. The electric field could oscillate in the y-direction, while the magnetic field oscillates in the z-direction. This configuration clearly shows that both fields are perpendicular to each other and to the direction of propagation.

4. **Conclusion**:
- Since the assertion is true (electromagnetic waves are indeed transverse) and the reason is also true (the electric and magnetic fields are perpendicular to each other and the direction of propagation), we can conclude that both the assertion and reason are true.
- Furthermore, the reason correctly explains why the assertion is true.

5. **Final Answer**:
- Therefore, the correct option is that both assertion and reason are true, and the reason is the correct explanation of the assertion.
