Question

Quizplus · Accepted Answer

The speed of sound in air is given by the formula v = fλ, where f is the frequency and λ is the wavelength. For a frequency of 500 Hz and a wavelength of 0.68 m, the speed of sound is 340 m/s. The speed of sound in air at 15°C is approximately 340 m/s, indicating the air temperature is 15°C.
