In 3-5 complete sentences, compare the three ways that waves change direction.

Reflection is the change in direction of a wave between two different objects such that the wave returns to the medium from which it began. In other words, the waves are sent back towards the source. Sound waves, light waves, and water waves can all be reflected.

Explanation:

Incident Ray – the wave/ray traveling towards a surface

Angle of Incidence – the angle at which the traveling wave/ra

y hits a surface

Equal (or Normal) – divides the two rays (incident / reflected) into two equal angles

Angle of Reflection – the angle at which the reflected wave returns towards the original medium

Reflected Ray – the wave/traveling away from the “hit” surface, and now traveling towards the original medium
