Cookie Notice That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. The units of frequency are called hertz (Hz). Low frequency (long wave length) sound waves in the atmosphere (or water- ask any whale!) Therefore, longer wavelengths diffract more than shorter wavelengths. 4 What are two reasons for frequency translation? Do low frequencies carry farther than high frequencies?

For low frequencies subwoofers are large and have a resonating chamber which simply isn't an option with headphones that must produce a large range of sound frequencies in a small space. Why do high frequency signals travel longer than low frequency signals? Waves of shorter wavelength spread out (diffract) less after passing through the slits, and the short wavelength leads to a smaller angle at which constructive interference (one wavelength path difference between the two waves) will occur. It travels faster in water than in air, for instance, and travels faster in wood than in water. Perhaps also the low frequencies resonate with the walls of the building?
