Question

audible range of frequency is 20 Hz to 2KHz .find the range of wavelength corresponding to this frequency given velocity of sound is 350m/s.



a
Answer me Harry up

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


HOPE TO HELPFUL FOR YOU

Answer 2

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
