This is a multiple choice answer as classified in NCERT Exemplar
(c) Speed of sound wave in a medium v
Clearly when temperature changes speed also changes
As v= as frequency remains constant and speed changes so wavelength changes

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).
