$\huge\mathfrak{Question:-}$
A person has a hearing range from 20 Hz to 20 kHz. What are
the typical wavelengths of sound waves in air corresponding
to these two frequencies? Take the speed of sound in air as
344 m s.​

Answer 1

hyy dude

Speed = wave length * frequency

Wave length = Speed / frequency

Therefore :

( 1 ) Frequency of sound = 20 Hz

Speed of sound = 344

The wave length will be = 344/20 = 17.2 m

( 2 ) If frequency of sound = 20khz ( 20,000 Hz )

Speed of sound = 344

The Wave length will be =

344/20,000 = 0.0172
