Question

the time period of a sound wave travelling in a medium is T if
at a given instance (t=o) a particular region in the medium has
minimum density the density of this region will be maximum and
minimum respectively again at t=T and t=2T respectively true or
false

Kranav Sharma · Accepted Answer

Time period is time taken by one complete oscillation to occur
Now, as the wave starts from compression, at t = 0 the density of
the medium would be high while at t = T/2 there will be a
rarefaction and the density would be the lowest Now again at t = T
the density would be highest and so on such that both at T and 2T
there will be compression wave and thus medium would have maximum
density
Thus, the above given statement is false

the time period of a sound wave travelling in a medium is T. if at a given instance (t=o) a particular region in the medium has minimum density. the density of this region will be maximum and minimum respectively again at......t=T and t=2T respectively....true or false
