Question

Audible frequency have a range of 20 hertz to 20000 hertz . Express this range in terms of velocity 340m/s.​

Answer 1

Hey mate.....

here's the answer....

Velocity= 340 m/s

Frequency = 20 Hertz to 20,000 Hertz.

Time = 1/ frequency

Time = 1/20 , 1/20000

= Velocity/frequency

340/20 = 17m ..... 340/20,000 = 0.017m

17m to 0.017 m

Hope this helps❤

Answer 2

$\boxed{\boxed{\huge{\mathfrak{\purple{Solution}}}}}$

Range of Audible Frequency = 20Hz to 20000Hz..

Given,

Velocity of sound in air = 340m/s..

For frequency = 20Hz,

Speed = Wavelength * Frequency

Wavelength = Speed/Frequency

= 340/20

= 17m

For frequency = 20000Hz,

Speed = Wavelength * Frequency

Wavelength = Speed/Frequency

= 340/20000

= 0.017m

Therefore,

In terms of velocity 340m/s, the audible range of human ear =

17m to 0.017m...
