An average adult can hear sounds with frequencies between 20 waves per second and 16,000 waves per second. What is the wavelength, in meters, of a sound wave with a frequency of 20 waves per second?
Accepted Solution
A:
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 [tex]3\times 10^{8}[/tex].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 [tex]3\times 10^{8}[/tex] = 20 × λ λ = [tex]\frac{3\times 10^{8}}{20}[/tex]λ = 15,000,000 m
