Solution

Lightis a type of transverse wave and in transverse waves particles oscillate up and down about their mean position as the wave travels.

Sound wave is a mechanical wave, which means, unlike light, it needs a medium for propagation.

Three statements regarding the propagation of sound waves.

I Sound waves propagate through a series of crests and troughs.

II Sound waves require a material medium for their propagation.

III The propagation of sound waves is attributed to the motion of particles.

Among the given statements,

X - d i r e c t i o n

y = \frac{1}{2 + x^{2}}

t = 0

y = \frac{1}{[2 + (x - 1)^{2}]}
