This is a multiple choice answer as classified in NCERT Exemplar
(c) Due to presence of moisture density of air decreases.
As we know speed of sound in air v=
So v
v2/v1=
2 (moist air)< 1 (dry air)
So v2>v1
So speed of sound wave increases with increase in humidity

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).
