Question

the audible range of frequency of an human ear in form 20hz to 20khz calculate the wavelength

Answer 1

speed of sound= wavelenth * frequency

when frequency is 20Hz

 

then wavelength=344/20=17.2m

 

when frequency is 20KHz

then wavelength= 344/20000    (20KHz = 20000Hz)

=0.0172m

Answer 2

Answer:

Convert this into corresponding wavelength range.

The speed of sound at ordinary temperature is 340m/s.

Thus, the audible wavelength range is 0.017 m to 17 m
