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:

**Step 1: Understanding the Production of Electromagnetic Waves**
Electromagnetic waves are produced by the acceleration of charged particles. When a charged particle, such as an electron, accelerates, it generates a changing electric field. This changing electric field, in turn, induces a magnetic field. The interplay between these changing electric and magnetic fields propagates outward as an electromagnetic wave.

**Step 2: Visualizing the Electric and Magnetic Fields**
In a plane electromagnetic wave, the electric field (E) and magnetic field (B) oscillate perpendicular to each other and also perpendicular to the direction of wave propagation. If we consider the wave propagating along the X-axis, we can represent the oscillations of the electric and magnetic fields.
