A disturbance that transfers energy from one place to another.

A line joining points on a wave that are at the same stage of an oscillation.

The distance between corresponding points on consecutive waves, such as one crest and the next.

The way the intensity of emitted radiation is spread across different wavelengths.

The movement or progression of a disturbance that transfers energy from one place to another.

The distance travelled by a wave each second, measured in metres per second (m/s).

The distance travelled by a wave each second, measured in metres per second (m/s).

The weight of an object: the force on it due to gravity, measured in newtons (N).

A compact, hot remnant left after a Sun-like star sheds its outer layers; it no longer sustains fusion.

The transfer of energy when a force causes an object or boundary to move through a distance.

Energy transferred when a force moves an object through a distance in the direction of that force.

Energy transferred when a force causes an object to move through a distance.

A sensitive instrument that detects small currents and shows their direction using deflections on either side of zero.
