Question

in sound waves, the distance between compressions is called the wavelength. what is the distance between rarefactions called? ○ speed ○ frequency ○ amplitude ○ wavelength

Explanation:

In a sound wave (a longitudinal wave), compressions and rarefactions are alternating regions. The distance between two consecutive compressions or two consecutive rarefactions is defined as the wavelength. Speed is the rate of wave propagation, frequency is the number of waves per unit time, and amplitude is the maximum displacement from the equilibrium. So the distance between rarefactions is also wavelength.

Answer:

D. wavelength (assuming the options are labeled A - D with D being wavelength; if the original options had different labels, adjust accordingly, but based on the options given, the correct one is the "wavelength" option)
