Which of the following statements are TRUE of the speed of sound? Identify all that apply. The speed of a sound wave depends upon its frequency and its wavelength. In general, sound waves travel fastest in solids and slowest in gases. Sound waves travel fastest in solids (compared to liquids and gases) because solids are more dense. The fastest which sound can move is when it is moving through a vacuum. If all other factors are equal, a sound wave will travel fastest in the most dense materials. A highly elastic material has a strong tendency to return to its original shape if stressed, stretched, plucked or somehow disturbed. A more rigid material such as steel has a higher elasticity and therefore sound tends to move through it at high speeds. The speed of sound moving through air is largely dependent upon the frequency and intensity of the sound wave. A loud shout will move faster through air than a faint whisper. Sound waves would travel faster on a warm day than a cool day. The speed of a sound wave would be dependent solely upon the properties of the medium through which it moves. A shout in a canyon produces an echo off a cliff located 127 m away. If the echo is heard 0.720 seconds after the shout, then the speed of sound through the canyon is 176 m/s. The speed of a wave within a guitar string varies inversely with the tension in the string. The speed of a wave within a guitar string varies inversely with the mass per unit length of the string. The speed of a wave within a guitar string will be doubled if the tension of the string is doubled. An increase in the tension of a guitar string by a factor of four will increase the speed of a wave in the string by a factor of two. An increase in the linear mass density of a guitar string by a factor of four will increase the speed of a wave in the string by a factor of two.
