Answer 2

Solution:-

The audiable waves of a man is 20Hz to 20,000Hz.

The speed of sound in the air is 340m/s.

As we know that,

Speed of sound= Wavelenth × Frequency

When frequency is 20Hz

then wavelength=340/20=17 m

When frequency is 20KHz

then wavelength

= 340/20000 (20KHz = 20000Hz)

=0.0170m

[Answer:- 0.0170 m]
