Using Huygen's construction, draw a figure showing the propagation of a plane wave reflecting at the interface of the two media. Show that the angle of incidence is equal to the angle of reflection.

Explanation

To solve the problem using Huygen's construction and demonstrate that the angle of incidence is equal to the angle of reflection, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Media and the Interface**:
- Consider two media, Medium 1 and Medium 2, separated by a boundary surface, which we will denote as line XY.

2. **Draw the Incident Wavefront**:
