Question

Q How does the following factors affect it at all the velocity of sound in air ?

1. pitch of sound
2. temperature of air
3. pressure of air
4. moisture of air

Answer 1

Dear Student

The speed of sound in air is not affected by Amplitudes, frequency, phase, loudness, pitch, or quality.

The vibration of molecules is accelerated with rise in temperature . Thus, increase in vibrational motion of particles means there would be an increase in speed of sound.

Speed of sound in an ideal gas doesn't depend on pressure of medium.

Humidity decides the number of water molecules in air. Speed of sound is directly proportional to humidity. Because of humidity , there is 0.1 to 0.6 times change in speed of sound.
