How does a charge q oscillating at certain frequency produce electromagnetic waves ?
Sketch a schematic diagram depicting electric and magnetic fields for an electromagnetic wave propagating along the Z-direction.

Explanation

To understand how a charge \( q \) oscillating at a certain frequency produces electromagnetic waves, we can break down the process into several steps:

### Step-by-Step Solution:

1. **Understanding Charge Oscillation**:
- When a charge \( q \) oscillates, it moves back and forth around a central point. This motion creates a changing electric field around the charge.

2. **Creation of Electric Field**:
