Question

Quizplus · Accepted Answer

Audible sound waves typically have wavelengths ranging from a few inches to a few feet in air, correlating with the frequencies humans can hear (approximately 20 Hz to 20 kHz). The speed of sound in air is about 343 meters per second, and wavelength is related to the speed of sound and frequency by the equation wavelength = speed/frequency.
