Question

Iii. A sound wave can be modelled by using a slinky spring. A wavelength in this model is...

a. the distance between a rarefaction and a compression.
b. the length of one compression.
c. the length of one rarefaction.
d. the distance between two rarefactions,

Answer 1

Answer: d. the distance between two rarefactions,

Step-by-step explanation:

Wavelength is the distance between two identical adjacent points in a wave. This means that it is the distance between two adjacent compressions or two adjacent rarefactions.

Wavelengths are inversely related to frequency because the longer the wavelength, the less the number of wave cycles per second.
