Science
Reflection.
Definition
Reflection occurs when a wave bounces off a surface. The law of reflection states that the angle of incidence equals the angle of reflection, both measured from the normal (perpendicular) to the surface.
Examples
Real-world.
- 1 Seeing your image in a flat bathroom mirror
- 2 A laser beam bouncing off a mirror at the same angle it hit
- 3 The Moon reflecting sunlight to appear bright in the night sky
Key Fact
Law of reflection: angle of incidence (θᵢ) = angle of reflection (θᵣ)
