Question

The highest frequencies humans can hear isabout 20000 Hz.What is the wavelength of sound in airat this frequency?The speed of sound is310 m/s.

Answer 1

Given

The highest frequency human can hear is f=20000 Hz

Speed of the sound,v=310 m/s

To find

The wavelength

Step-by-step explanation

We know,

The wavelength is given by

`\begin{gathered} \lambda=(v)/(f) \\ \Rightarrow\lambda=(310)/(20000) \\ \Rightarrow\lambda=0.0155\text{ m} \end{gathered}`

Conclusion

The wavelength is 0.0155 m
