Physics - waves

Energy input into a medium, resulting in a disturbance of the medium.

Any substance capable of transmitting energy

Repeated vibrations.

When an object is experiencing repetitive vibrations.

When the energy input is perpendicular to the resulting wave's motion

When the energy input is parallel to the resulting wave's motion.

When the energy input displaces the particles in a circular motion around a central axis.

The number of cycles in a second. Also the pitch of the sound.

The number of seconds in a cycle.

When transmitted and reflected waves are in sync.

The mechanical disturbance of a medium resulting in vibrations of the medium within an amplitude and frequency that is audible to a specific device (our ears).

• Three-dimensional, longitudinal waves.
