Homework Question please help it physical science?
On a hot summer day (30 degrees Celsius), 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? (10 points)

The wing beats are 600 cycles per second. That is a frequency of f = 600 Hz.
The speed of sound at 30°C is c = 331.3 + 0.6 × 30 = 349.3 m/s.
Wavelength λ = c / f = 349.3 / 600 = 0.58 m.
