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 and frequency. 1  Light is measured by its wavelength (in nanometers) or frequency (in Hertz). 2  One wavelength. equals the distance between two successive wave crests or troughs. 3  Frequency (Hertz) equals the number of waves that passes a given point per second.
