This is a multiple choice answer as classified in NCERT Exemplar
(d) Due to compression and rarefactions density of the medium changes.at compressed regions density is maximum and at rarefactions density is minimum
As density is changing so boyle, s law not obeyed
Bulk modulus remains same
The time of compression and rarefaction is too small so no transfer of heat.

The acceleration of wave is g/2. Its speed increases as it moves up. So answer is (2)
Distance between successive compression and rarefaction is λ/2
.
Both points B and G are moving up and are at same distance from equilibrium position at the instant.
Equation of component waves are
y = Asin (ωt – kx) and y = Asin (ωt + kx)
So speed of component wave is (ω/k).
