Front

Sound travels in this type of wave.

Back

Longitudinal / compression wave: A type of wave where the particle displacement is parallel to the direction of wave propagation, commonly seen in sound waves.

Front

When light bounces off an object.

Back

Reflection: The bouncing back of light when it hits a surface. For example, a mirror reflects light.

Front

The distance between two points in a wave that follow each other.

Back

Front

The process of light bending as it passes from one medium to another.

Back
