How are electromagnetic waves produces by oscillating charges ? Draw a sketch of linearly polarized EM waves propagating in z-direction. Indicate the direction of oscillating electric and magnetic fields

Explanation

### Step-by-Step Solution:

1. **Understanding Oscillating Charges:**
- An oscillating charge, such as a charge \( Q \), moves back and forth with a certain frequency \( \mu \). This motion creates a changing electric field around the charge.

2. **Production of Electric Fields:**
- As the charge oscillates, it generates an electric field \( \mathbf{E} \) that varies in space and time. The direction of the electric field is determined by the direction of the charge's oscillation.
