Answer 2

Answer:

Propagation of Sound

The travelling of sound is called propagation of sound.

Sound is propagated by the to and fro motion of particles of the medium.

When an object vibrates, the particles around the medium vibrate. The particle in contact with the vibrating object is first displaced from its equilibrium position. Each particle disturbs the other particle in contact. Thus, the disturbance is carried from the source to the listener.

Propagation of sound

Only the disturbance produced by the vibrating body travels through the medium but the particles do not move forward themselves.

Wave

Wave is a phenomenon or disturbance in which energy is transferred from one point to another without any direct contact between them. For example: Heat, light and sound is considered as a wave.

Types of Waves

On the basis of direction of propagation, waves are categorized into two parts:

(i) Longitudinal waves: These are the waves in which the particles of the medium vibrate along the direction of propagation of the wave. For example: sound wave.

(ii) Transverse waves: In this type of wave the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave. For example: waves produced in a stretched string.

Another type of waves which do not require any medium for propagation are called electromagnetic waves. These waves can travel through vacuum also. For example, light waves, X-rays.
