A sound wave travels at a speed of 330 m/s, if its wavelength is 1.5cm, what is the frequency of the wave? Will it be audible to humans?

Answer:
given wavelength = 1.5cm = 0.015m. therefore frequency = velocity/ wavelength. hence frequency of given sound wave = 330/0.015 = 22,000Hz. No, it's not audible because the audible range for humans is 20 hz to 20,000 hz and this given wave has higher frequency than our audible range so it's inaudible to us.

Answer:
since Frequency=speed/wavelength
=330/1.5×10²
=33000/1.5
=22000 HZ
Since human audible range is from 1500-20000HZ
therefore
22000 HZ is not audible.
