A plane wavefront is incident on a plane reflecting surface at an angle of `30^(@)`. What angle will the reflected rays make with the reflecting surface ?

Explanation

To solve the problem, we need to understand the behavior of light when it reflects off a surface. Here’s a step-by-step solution:

### Step 1: Understand the Given Information
We have a plane wavefront incident on a reflecting surface at an angle of \(30^\circ\). This angle is the angle of incidence (\(i\)).

### Step 2: Identify the Normal Line
The normal line is an imaginary line perpendicular to the reflecting surface at the point of incidence. Since the angle of incidence is measured from the normal, we can visualize the situation as follows:
- The angle of incidence \(i = 30^\circ\) is measured from the normal.
