A disturbance that transfers energy from one place to another without transferring matter.

A material in which a wave travels.

The highest points on a transverse wave.

The change in direction of a wave when it travels by the edge of an object or through an opening.

The number of wavelenghts that pass by a point each second.

The transfer of energy by a wave to the medium through which it travels.

The bouncing of a wave off a surface.

The change in direction of a wave that occurs as the wave changes speed when moving from one medium to another.

The passage of light through an object.

Occurs when waves that overlap combine, forming a new wave.

Regions of a longitudinal wave where the particles in the medium are closest together.

Regions of a longitudinal wave where the particles are farthest apart.

A wave that can travel through empty space and through matter.

A wave is the maximum distance that the wave moves from its rest point.

A wave that can travel only through matter.

A wave in which the disturbance is perpendicular to the direction the wave travels.

Makes the particles in a medium move parallel to the direction that the wave travels.

When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.

A wave is the distance from one point on a wave to the same point on the next wave.
