Question

What is the angle of incidence if a reflected wave bounces off a mirror with an angle of reflection equal to 55 degrees?

Answer 1

Answer;

55 degrees

Explanation;

• The angle of incidence is 55 degrees as the angle is equal to the bouncing or reflection angle. That is; Angle of incidence= angle of reflection.
• The angle of incidence is the angle between the incident ray and the normal while the angle of reflection is the angle between the reflected ray and the normal.
• According to the law of reflection, when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
