AI Generated Solution

To solve the question "Angle of incidence = ..........", we will follow these steps: ### Step-by-Step Solution: 1. **Understanding the Concept**: The angle of incidence is defined as the angle formed between the incoming ray of light and the normal (a line perpendicular) to the surface at the point of incidence. 2. **Identify the Law of Reflection**: According to the law of reflection, when light strikes a smooth surface, it reflects off that surface. The first law of reflection states that the angle of incidence is equal to the angle of reflection. ...
