Question

[Q.6] Define velocity of sound.
...
[Q.7] What is the range of audible, infra and ultra sound?​

Answer 1

Explanation:

The sound velocity through a given material is the distance that the sound energy will propagate in that material in a given time, and it is a function of material density, acoustic impedance and temperature

Answer 2

Answer:

Ans 6..The velocity of sound is a vector whose magnitude is the speed of sound and whose direction is normal to the surface of constant phase .

Ans 7..The range of infra sound is below 20 Hz , the range of ultra sound is above 20,000 Hz and the range of audible sound is 20 Hz-20 KHz.
