When light bounces off a surface at the same angle at which it hits, what phenomenon is occurring?

Refraction
Transmission
Reflection
Diffraction

The correct answer is: Reflection

When light bounces off a surface at the same angle at which it hits, the phenomenon that occurs is reflection. This process involves the change in direction of light waves when they encounter a surface, causing them to travel away from it. The angle at which the light strikes the surface, known as the angle of incidence, is equal to the angle at which it reflects away, referred to as the angle of reflection. This principle can be observed with everyday mirrors, where the smooth surface allows for clear and defined reflections. Refraction, on the other hand, involves the bending of light as it passes from one medium to another, changing its speed and direction. Transmission refers to the passage of light through a medium without being absorbed or reflected significantly. Diffraction involves the bending of light waves around obstacles or through openings, leading to patterns that aren't related to the simple bouncing behavior of reflection. Understanding these distinct concepts helps clarify why reflection is the correct answer in this context.
