Which of the following choices correctly describes the behavior of the sound wave as it moves from metal to air? Long wavelengths bend around objects that are smaller then themselves, while short wavelengths reflect off of or are absorbed by those same objects. The speed of sound depends on proper-ties of the medium such as bulk modulus, density, and temperature. Cookies are only used in the browser to improve user experience. Amplitude Of A Wave; Sound Waves; Frequency/ Pitch of the Sound Waves. The frequency range for the human hearing is 20 to 20.000 Hz. Sound is also shown at the spectrum chart, but it is no electromagnetic radiation. The formula used for the calculation is wavelength = speed of sound / frequency, λ = c / f. Example: the standard pitch a with 440 hertz has a wavelength in air of 78 centimeters and in water of 3.373 meters. This number represents the equilibrium undisturbed position … These compressions and rarefactions travel through the air in the form of longitudinal waves, which have the same frequency as the sound source.
