Wavelength λ of a wave is defined as the distance between two consecutive compressions or rarefactions . As we know that between two consecutive compressions , there is a rarefaction or vice-versa , therefore distance between a compression and consecutive rarefaction will be λ/2 .
given λ/2=100m ,
or λ=2×100=200m

Answer:
10cm
Explanation:
(8-3) rarefactions=50cm(wavelength)
=5 rarefaction=50cm
= 1 rarefaction=(50/5)cm
=1 rarefaction = 10cm
