How is electromagnetic wave produced ? Draw a sketch of a plane e.m. wave propagating along X-axis depicting the directions of the oscillating electric and magnetic fields.

Explanation

### Step-by-Step Solution:

1. **Understanding Electromagnetic Wave Production**:
- Electromagnetic (EM) waves are produced by accelerating charged particles. When a charged particle accelerates, it disturbs the surrounding electric and magnetic fields, resulting in the generation of EM waves.

2. **Key Concept**:
- An oscillating charge creates a changing electric field, which in turn induces a magnetic field. This process continues, allowing the wave to propagate through space.
