Question

Distance between a compression and adjoining rarefactions in a pressure wave
is
a)
1
b)
i
d)
3​

Answer 1

The distance between compression and adjoining rarefactions in a pressure wave  is known as wavelength.

• The wavelength of the particular wave is the distance between the area of compression and the rarefaction. The distance from a compression to the next longitudinal refraction of wave is 1/2 wavelength.
• The wavelength λ is referred to as the distance between adjoining compressions and rarefactions. Thus, this means that distance between both of them is λ/2
