Properties or characteristics of a wave include:

1. Reflection of Waves:

reflected ray 3

A wave is reflected when it hits a hard surface or bounces back after hitting an obstacle.

reflection by plane surface
Reflection by a plane surface

When incident wavefronts hit a hard surface, they are reflected such that the angle of incidence of the wave is equal to the angle of reflection of the wave.

2. Refraction of Waves:

When a wave travels from one medium to another medium, the velocity of the wave changes or the wave bends or changes direction.
