Question

Identify the parts which vibrate to produce sound in the following instruments.

Item-1	Item-2
Flute	Stretched membrane
Violin	Stretched strings
Tabla	Air columns

Answer 1

Hint: We all know that sound is produced by vibrating objects. When the object vibrates it sets the particles of the medium around it vibrating. Different types of instruments produce the melody sound by the vibration of strings, vibration of a membrane, vibration of the air column.

Complete step-by-step solution:
We can define sound because of the kind of energy that produces a sensation of hearing in our ears.
Medium is termed the substance through which sound waves travel. The medium is of varied kinds. It is often a solid, liquid, or gas.
The Sound propagates through it and moves from the point of generation to the listener. As an example, the radio may be a source of the sound, and therefore the ear of the listener acts as the receiver of the sound.
A particle of the medium in grip with the vibrating object is first displaced from its equilibrium position. After that, it exerts a force on the adjacent particles. As a result, these adjacent particles get moved from their position of rest.
Here particles within the medium transfer their energy from one particle to a different particle by vibration. There’s no movement of particles from one place to another place.
We can take the instance of guitar strings. When these kinds of strings are vibrated using hand movement it produces a melodious sound that soothes the mind. Different instruments produce sound supported by the vibration of a membrane, air, or strings.
From the above information, let's fill in the chart given:

Item-1	Item-2
Flute	Air columns
Violin	Stretched strings
Tabla	Stretched membrane

Note: Sounds needed may be a medium for the propagation of it. Sound cannot travel through a vacuum. Sound waves are longitudinal waves. A wave could be a disturbance that moves through a medium when the particles of the medium set neighboring particles into motion. The particles carry the disturbance forward but they do not move forward by themselves. Sound travels through the air most. There are some characteristics of the sound wave. They’re frequency, amplitude, speed, wavelength, intensity, quality of sound.
