On a hot summer day (30 degrees Celcius), a pesky little mosquito produced its warning sound near your ear. The sound is produced by the beating of its wings at a rate of about 600 wing beats per second. What is the frequency in Hertz of the sound wave? What is the wavelength of the wave?

f=600 Hz,
speed of sound at 30 ºC v= 348,9 m/s
λ = v/f= 348.9/600= 0.58 m.
