properties of wave (revisit)

A single disturbance that moves from point to point through a medium is called a ___.

• period

• periodic wave

• wavelength

• pulse

If the particles of the medium are vibrating to and fro in the same direction of energy transport, then the wave is a ____ wave.

• longitudinal

• sound

• standing

• transverse

When the particles of a medium are vibrating at right angles to the direction of energy transport, then the wave is a ____ wave.

• longitudinal

• sound

• standing

• transverse

A transverse wave is traveling through a medium. See diagram.
