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.
As the wavelength increases, frequency decreases. A wavelength is the distance from, say, a crest to a crest, or perhaps a trough to a trough. Frequency is essentially how many waves or how many cycles of a wave there are per unit of time, and we usually apply the term cycles per second or Hertz (which means cycles per second) to it.
