Wavelength :
(a) In sound waves the combined length of a compression and an adjacent rarefaction is called its wavelength.
(b) The distance between the centres of two consecutive compressions or two consecutive rarefactions is also called its wavelength.
(c) It is denoted by the Greek letter lamda λ. Its SI unit is metre.
Frequency :
(a) No. of complete waves produced in one second or number of vibrations per second is called frequency.
(b) Number of compressions or rarefactions passed in one second is also frequency.
• Frequency of wave is same as the frequency of the vibrating body which produces the wave.
• The SI unit of frequency is hertz (Hz). The symbol of frequency is v (nu).
• 1 Hertz : One Hz is equal to 1 vibration per second.
• Bigger unit of frequency is kilohertz kHz = 1000 Hz.
