Sound from source A has twice the frequency of sound from source B. Compare the wavelengths of sound from the two sources.

Solution 9E Step 1 : We need to compare the wavelength of waves coming from two different sources We know that v = f Here wavelength v speed of sound f frequency The speed of the waves remains same, and frequency of one source is double than the other Hence we write for two waves as f = 2f × We get 1 2f = 2
