Question

a sound wave travels at a speed of 339 metre per second if its wavelength is 1.5 CM its frequency is

Answer 1

Hey there!

Speed of sound, v = 339 m s−1

Wavelength of sound,= 1.5 cm = 0.015 m

Speed of sound = Wavelength × Frequency

Frequency = Speed of sound/Wavelength

Frequency = 339/0.015

= 22600 Hz.

IT'S NOT AUDIBLE AS ITS FREQUENCY IS MORE THAN THE NORMAL RANGE (20 Hz - 20 kHz)
WHICH HUMAN BEINGS CAN HEAR...
