Solution
The frequency of a sound wave will decrease if the wavelength of that sound wave is increased. This is due to the inverse relationship between frequency and wavelength, which is expressed in the formula v = fλ where v is velocity, f is frequency, and λ is wavelength. If the speed of sound remains constant and the wavelength increases, the frequency must decrease to maintain the equation's balance.
