Understanding the Concepts

* Angle of Incidence: The angle between the incoming ray of light (incident ray) and the normal (a line perpendicular to the mirror's surface) is called the angle of incidence.

* Angle of Reflection: The angle between the reflected ray and the normal is called the angle of reflection.

* Law of Reflection: The angle of incidence is always equal to the angle of reflection.

Solving the Problem

1. The given angle is 30 degrees with the surface. This means the angle of incidence is 60 degrees (90 degrees - 30 degrees).

2. Applying the Law of Reflection: The angle of reflection will also be 60 degrees.

Therefore, the angle of reflection is 60 degrees.
