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.
The frequency and wavelength are simply related by the speed of light, so they're just different ways of measuring the same thing: [math]\nu = c/\lambda[/math] And the energy of the photon is just: [math]E = h\nu = hc/\lambda[/math] The condition for a photon to be wave-like is that it is delocalized (spread out) in space. Under those conditions, the wavelength corresponds to the spacing between the peaks of amplitude of the wave.
