Question

a person has a hearing range from 20 hertz to 20 kilohertz. what are the type pickle wavelength of sound waves in their corresponding to this 2 frequencies ? Take the speed of air in as 344m/s​

Answer 1

Answer:

speed 344

frequency 20hz

weavlength ?

speed = frequency *wavelength

344=20* wavelength

344/22 = wavelength

17.2 wavelength

Speed 344

frequency 29 khz

20*1000

2000hz

speed - frequency* wavelength

344 =2000 *wavelength

wavelength = 0.0172
