A mosquito flaps its wings 600 vibrations per second, which produces the annoying 600-Hz buzz. Given that the speed of sound is 340 m/s, how far does the sound travel between wing beats? In other words, find the wavelength of the mosquito’s sound.
Solution 5P The frequency of the mosquito is, = 600 hertz This beating of wings create sound waves which travel at the speed of sound in air which is, V = 330 m/s. We know the relation between frequency, wavelength and velocity of a wave which is true for any kind of waves. That is, V = ---------------------------(1) Where is the wavelength of the wave (sound wave). From equation (1), = V / = 330 / 600 = 0.55 meters. CONCLUSION: The wavelength of the mosquito’s sound is 0.55 meters.
