Answer the following question given this paragraph: Reflected waves have the same speed and frequency as the original waves before they were reflected. However, the direction of the reflected waves is different. When waves strike an obstacle head on, the reflected waves bounce straight back in the direction they came from. When waves strike an obstacle at any other angle, they bounce back at the same angle but in a different direction. This is illustrated in the Figure below . In this diagram, waves strike a wall at an angle, called the angle of incidence. The waves are reflected at the same angle, called the angle of reflection, but in a different direction. Notice that both angles are measured relative to a line that is perpendicular to the wall. Q: When waves are reflected at the same angle, what is it called? Choices: - field of view - refraction - phenomenon of reflection - angle of reflection A:
The answer to this question is:
angle of reflection
