SUMMARY
The angle of incidence is defined as the angle between an incident ray and the normal to a reflecting surface. In this discussion, if the angle between the incident ray and the reflecting surface is 23°, the angle of incidence is calculated as 90° - 23°, resulting in an angle of incidence of 67°. Understanding the relationship between the angle of incidence and the normal line is crucial for solving problems related to reflection.
