Question

1. What is vibration?
2. What is a sound wave?
3. What is a medium of transmission of sound?​

Answer 1

Answer:

hope this helps

Explanation:

1.Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem. The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

2.A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords.

3.Sound can propagate through a medium such as air, water and solids as longitudinal waves and also as a transverse wave in solids.

Answer 2

Answer:

vibration -Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem. The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

sound wave- Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. ... The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.

transmission of sound- The most usual medium of sound transmission is air, but any substance that can be compressed can act as a medium for sound propagation. A fundamental characteristic of a wave is that it carries energy and momentum away from a source without transporting matter from the source.
