Question

Name the parts that vibrates to produce sound in the following
1. Drums
2. Sitar
3. Flute

Answer 1

Hint: Instruments produce sounds in one way or another, and all sounds are vibrations that flow through the air around us (for humans anyway). Our eardrum, which is a thin vibrating membrane, transforms these vibrations.
In short, a musical instrument may vibrate, or contain a portion that vibrates, or may amplify and/or modify another vibration. More waves are created by quicker vibrations, and the rate at which they move is measured in hertz (Hz), or cycles per second. The higher the pitch, the higher the frequency (or the more ‘bumps' in the waveform).

Complete answer:
Objects that vibrate make sound. In humans, the voice box, also known as the larynx, is a portion of the throat that creates sound. It has two vocal cords that are stretched over the larynx, leaving a thin opening for the air to pass through. The vocal cord vibrates and produces sound when the lungs force air through the slit.
(1) Drums – Its stretched membrane
(2) Sitar – Its strings.
(3) Flute – Its long hollow pipe.

Additional information:
Music and sound are an integral element of our daily lives. A sound is a sort of energy that allows us to hear things. Sound is detected using the ears. The vibrations of things produce sound, which is then transmitted over a medium from one spot to another. Vibration refers to an object's to-and-fro or back-and-forth motion. Vibrations are caused by the movement of objects. We can see the vibrations with our naked eyes in many circumstances. While their amplitude is often so little that we cannot see them, we may feel them.
For example- The strings of a guitar vibrate and make sound when they are plucking them. It generates sound, which is carried through the channel of air.

Note:
The larynx, or voice box, is located in the upper region of the human body and produces voice. The larynx can be found near the top of the windpipe. Two vocal cords that cross the larynx stretch in such a way that air can only pass through a tiny area between them. When a person speaks, the muscles in their larynx are stretched, and the opening narrows. The voice chords vibrate when air is forced through the slit. The vibrations in the vocal cords increase as they are tightened, resulting in a louder loudness of sound. It is for this reason that the human voice has a variety of pitches.
