A sound wave has a frequency of 200 Hz and travels through air at a speed of 300 m/s. What is the wavelength of the sound wave?
Correct: C
The wavelength of the sound wave can be calculated using the formula λ = v/f, where λ is the wavelength, v is the speed, and f is the frequency. Given v = 300 m/s and f = 200 Hz, we can calculate λ = 300 / 200 = 1.5 m.
