Answer:
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
