Question

Given that the speed of sound in air is 330m/s ,calculate the frequency of a note which setup a wavelength of 5cm in air.Is this frequency within the limits of audibility of the human ear?

​

Answer 1

v = wavelength x frequency

330 = 5 . 10-² m x f

f = 6600 Hz

the frequency human is capable to hear- 20 Hz - 20. K Hz

so human can easily interpret note just like we interpret light

Answer 2

Step-by-step explanation:

v = wavelength x frequency

330 = 5 . 10-² m x f

f = 6600 Hz

the frequency that human can hear is about 20 Hz - 20000 Hz

so human can hear the note.
