An earthquake is started when two layers of rock under stress slip and wiggle past each other several times before coming to rest. This launches a wave through the rock, which violently wiggles the surface of the earth. If earthquake A has a frequency of $1$ Hz and earthquake B has a frequency of $2$ Hz$,$ which is the correct relation below between their wavelengths? $($Assume that the earthquake wave speed doesn't depend on frequency.$)$
