Question

4. The sound wave produced by a musical instrument is
not a monotone. Why? ​

Answer 1

Answer:

Sound is produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.

Explanation:

Answer 2

Due to high and low pressure areas the sound is not a monotone sound.

Explanation:

• Monotone sound is an unchanging tone.
• The sound produced by musical instruments is not monotone. The sound is produced by the vibration of particles.
• As the particles vibrate the surrounding particles in the medium also vibrate.
• As the particles move they move from high pressure area to low pressure area.
• These areas are called as compression and rarefaction.
• Due to high and low pressure area the sound is not a monotone sound.
