This article is about the basketball rule. For the food belief, see Five-second rule. In basketball, the five-second rule, or five-second violation, is a rule that helps promote continuous play. There are multiple situations where a five-second violation may occur.
Speed of sound which is the distance travelled by sound waves. Wavenumber which is the property of a wave. Wavelength which is the distance between each sound wave. Frequency which is the number of times a sound wave occurs.Wavelength is a measure of the distance between several sound waves and is used to measure the length of a sound wave in meters.peed of sound which is the distance travelled by sound waves. Wavenumber which is the property of a wave. Wavelength which is the distance between each sound wave. Frequency which is the number of times a sound wave occurs.
Wavelength is measured in metres. The number of waves passing every second is called its frequency, f. Frequency is measured in units called hertz (Hz) . The faster a wave is travelling the higher its frequency but the shorter its wavelength.
