Question

2. The loudness of sound depends on the amplitude of vibrations true or false​

Answer 1

Loudness of sound depends on the amplitude of vibration. Higher the amplitude of vibration, louder is the sound produced.

➠ Some quantities that are used to explain sound are period, frequency and amplitude. They are described below:

What is the Period of Sound?

A period can be said to be the time taken to do something. If an event occurs repeatedly then the event is said to be periodic. The time taken by the periodic event to repeat itself is known as the period. The time taken by the particle to complete one vibration cycle is the time period for that particle.

• Period = 1/Frequency

What is the Frequency of Sound?

The number of oscillations per second is known as the frequency of oscillation. Its unit is hertz and is denoted by Hz. The frequency of a wave in general means how frequently the particles of a medium vibrate when a wave moves through the medium.

• Frequency = 1/Period
• Frequency = 1/PeriodFrequency of Sound

What is the Amplitude of Sound?

The amplitude of a sound wave is the measure of the height of the wave. The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced. It is the distance between crest or trough and the mean position of the wave.
