Question

A sound wave has a wavelength of 4.0 m. The distance from a compression center to the adjacent rarefaction center is:
A. 0.4m
B. 2.0m
C. 4.0m

Answer 1

Answer:

distance between compression and rarefaction is given as d = 2 m

Explanation:

Distance between two consecutive compression and rarefaction is given as half of the wavelength

so we have

$d = \frac{\lambda}{2}$

here we know that wavelength is given as

$\lambda = 4 m$

$d = \frac{4}{2}$

$d = 2 m$
