An average adult can hear sounds with frequencies between 20 waves per second and 16,000 waves per second. What is the wavelengt
frez [133]

Answer:

The wavelength, of a sound wave with a frequency of 20 waves per second is 15,000,000 m.

Step-by-step explanation:

In this question, we have to calculate the wavelength of a sound wave of frequency 20 waves per second.

We know that  the speed of light in air/ vacuum is 3\times 10^{8}.

Now by the formula v = nλ , where v = speed of light in air/vacuum, n = frequency of the wave and λ = wavelength in meters,

we put the values

3\times 10^{8} = 20 × λ

λ = \frac{3\times 10^{8}}{20}

λ = 15,000,000 m
