The process of changing position.

Highest point on a transverse wave.

A material through which light does not pass.

A reflective sound wave.

A material in which a wave travels.

The maximum distance a wave varies from its resting position.

The passage of light through an object.

Region of a Longitudinal Wave where the particles of the medium are closest together.

The change of pitch when a sound source is moving in relation to an observer.

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

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

Occurs when waves overlap and combine to form a new wave.

Energy carried by an electromagnetic wave.

A material that allows most of the light that strikes it to pass through, but through which objects appear blurry.

The distance between one point on a wave and the nearest point just like it.

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

The SI unit of frequency, equal to one cycle per second.

The perception of how high or low a sound is; related to the frequency of a sound wave.

A rapid back-and-forth that can occur in solids, liquids, or gases.

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

Matter that emits no light at any wavelength.

The lowest point on a transverse wave.

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

A wave that can travel only through matter.

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

The bouncing of a wave off a surface.

The change in direction of a wave as it changes speed in moving from one medium to another.

Electromagnetic radiation that you can see.

A material that allows almost all of the light striking it to pass through, and through which objects can be seen clearly.

A longitudinal wave that can travel only through matter.

The region of a longitudinal wave where the particles of the medium are farthest apart.
