Determine the speed of sound in air for a given temperature. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display (Figure 17.4).
Describe the effects of temperature on the speed of sound. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display.

Learning Objectives. By the end of this section, you will be able to: Explain the relationship between wavelength and frequency of sound. Determine the speed of sound in different media. Derive the equation for the speed of sound in air. Determine the speed of sound in air for a given temperature.
Learning Objectives. By the end of this section, you will be able to: Define pitch. Describe the relationship between the speed of sound, its frequency, and its wavelength. Describe the effects on the speed of sound as it travels through various media. Describe the effects of temperature on the speed of sound.
21. Use the wavelength and the frequency to determine the speed of sound in air. 22. Find the value of the room temperature by reading your thermometer. Record the value of the temperature in degrees Celsius as part of your data. 23. Calculate the speed of sound from the formula: v = (331 + 0.606T) m/sec. Where T is the temperature in Celsius. 24.
Velocity of Sound = V = v (B/ ?) or = v (E/ ?). Therefore, it is the competition between the stiffness, measured by B (or E), and the inertia, measured by the density ?, that determines the speed of sound in a medium. Variation with Temperature.
