Answer 1

The angle of incidence of light incident on a smooth reflecting surface is equal to the angle of reflection.

Step-by-step explanation:

The angle of reflection of light incident on a smooth reflecting surface can be determined by the law of reflection, which states that the angle of incidence is equal to the angle of reflection. In this case, the angle of reflection is given as 55°, so the angle of incidence will also be 55°.

Therefore, the correct answer is: It's equal to 55°.
