3. The extent of vibration is called ______determines the________
of the sound produced.
​

Answer 1

★ Concept :-

What is Vibration? ↓

• The To and Fro motion of a body is called vibration.

• Sound is a form of mechanical energy that produces sensation of hearing.

• The sounds which are not pleasant to hear are called noise.

• Noise is an irregular combination of sounds which are 'unpleasant' to hear.

★ Required answers :-

2. The number of vibrations in one second is the frequency determines the Pitch of the sound produced.

3. The extent of vibration is called waves determines the Loudness of the sound produced$.$

★ Know more :-

• Sound can travel through solid liquids and gases.

• A wave is a disturbance produced in a medium that carries energy from one part of the medium to
• another without the transfer of matter.

• we have different types of waves. ↓

1. Mechanical wave.
2. Electromagnetic wave.
3. Transverse Wave.
4. Longitudinal wave.

Answer 2

Required Answer

2. The number of vibrations in one second is the frequency determines the amplitude of the sound produced.

3. The extent of vibration is called Frequency determines the pitch of the sound produced.

What is frequency ?

The frequency of a sinusoidal wave as the number of complete oscillations made by any element of the wave per unit time.

What is amplitude ?

The amplitude of a sound wave is the measure of the height of the wave. It is the distance between crest or trough and the mean position of the wave.

What is pitch ?

Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale.
