is a wave that is an oscillation of matter, and therefore transfers energy through a medium

# data[].attributes.body
When the particles of a wave move back and forth along the path the wave moves.

# data[].attributes.body
a wave vibrating at right angles to the direction of its propagation.

# data[].attributes.body
is the distance travelled per unit time by a sound wave as it propagates through an elastic medium

# data[].attributes.body
at which light waves propagate through different materials. In particular, the value for the speed of light in a vacuum is now defined as exactly 299,792,458 metres per second.

# data[].attributes.body
one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays

# data[].attributes.body
The portion of the electromagnetic spectrum that is visible to humans.

# data[].attributes.body
The number of waves produced in a given amount of time.

# data[].attributes.body
The maximum distance that the particles of a wave's medium vibrate from their rest position

# data[].attributes.body
The distance from any point on a wave to an identical point on the next wave
