The number of complete waves passing a point each second, measured in hertz (Hz).

The number of complete cycles occurring each second, measured in hertz (Hz).

Electricity supplied to homes through the UK mains is a.c. Its frequency is 50 Hz, and the domestic supply is about 230 V.

The number of waves passing a fixed point each second, measured in hertz (Hz).

Frequency is the number of complete vibrations or waves per second, measured in hertz (Hz).

The number of complete cycles produced each second, measured in hertz.

The number of complete wave cycles passing a point each second, measured in hertz (Hz).

Frequency describes repetition in time: how often cycles occur. Wavelength describes repetition in space: how far apart successive cycles are.

The number of complete waves passing a fixed point each second, measured in hertz (Hz).

The number of complete vibrations or waves each second, measured in hertz (Hz).

The number of complete oscillations or wave cycles passing a point each second.

The number of complete wave cycles or oscillations produced each second, measured in hertz (Hz).

The number of complete vibrations or waves passing a point each second, measured in hertz (Hz).

The number of waves passing a point each second, measured in hertz (Hz).

The number of complete waves passing a point each second.

The number of complete cycles occurring each second, measured in hertz.

The number of complete cycles passing a point each second, measured in hertz (Hz).

Four quantities describe this motion: amplitude tells us the size of the disturbance, wavelength its spatial length, frequency how often cycles occur and period how long one cycle lasts.

The number of complete waves or oscillations produced or passing a point each second.

The number of complete vibrations or wave cycles each second, measured in hertz (Hz).

The number of complete wave cycles passing a point each second, measured in hertz (Hz).

The number of complete cycles occurring each second, measured in hertz (Hz).

The number of waves passing a point each second.

The number of complete wave cycles passing a point each second, measured in hertz (Hz).

Their common speed does not make all regions identical: they have different wavelengths and frequencies, and interact differently with matter.

The number of complete wave cycles produced or passing a point each second, measured in hertz (Hz).

The number of complete waves produced by a source or passing a point each second, measured in hertz (Hz).

The number of complete waves produced each second, measured in hertz (Hz).

The number of complete vibrations or waves produced each second, measured in hertz (Hz).

The number of complete cycles occurring each second, measured in hertz (Hz).

The number of complete waves passing a fixed point each second, measured in hertz (Hz).

When sound enters another medium, its frequency stays the same; use its new speed to find its new wavelength.

Give the normal human hearing range as 20 Hz to 20 kHz; 20 kHz is 20,000 Hz. Do not confuse frequency with loudness.

For increasing frequency, give the order radio, microwave, infrared, visible light, ultraviolet, X-rays, gamma rays. For increasing wavelength, reverse it.
