• T3B5The wavelength of a radio wave relates to its frequency inversely, as the wavelength gets shorter the frequency increases. • Higher in frequency the shorter the distance between each wave. • T3B6The formula for converting frequency to wavelength in meters is the wavelength in meters equals 300 divided by frequency in megahertz. So, it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. While not negligible, this is not a strong dependence. At \(\text{0ºC}\), the speed of sound is 331 m/s, whereas at \(\text{20.0ºC}\) it is 343 m/s, less than a 4% increase. If the sound waves travel through air at a speed of v = 343 m/s, v=343m/s, what is the wavelength of the sound waves? 40 . A bat sends of a sound wave 100 kHz and the sound waves travel through air at a speed of v = 343 m/s . v=343m/s.
