Which of the following term is used for the wavelength of sound ?

  • A.Loudness
  • B.Pitch
  • C.Timbre
  • D.Reverberation

Answer: B

The key gives pitch for the term used for the wavelength of sound. The question is loosely worded, since pitch depends on the frequency, which is inversely related to the wavelength. Loudness depends on amplitude, timbre on the wave shape and reverberation is the persistence of sound in a space. This explanation follows the key.
