Unlike a longitudinal wave, the disturbance in a transverse wave is

The disturbance of molecules are perpendicular to wave motion

Explanation:

Transverse waves: in transverse waves all the medium moles vibrates perpendicular to the wave motion such that the net displacement of all molecules are zero.

While in longitudinal waves all the molecules will oscillate in the direction of wave propagation. All molecules transfer the energy from one point to other point while oscillating parallel to the wave propagation direction.

where is the circuit diagram ?

that would be because of both gravity and friction. so     c
