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. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength.
Speed of Sound in Gases, Liquids, and Solids. The speed of sound in air, at standard temperature and pressure, is 344 m/s (see speeds of sound in Table 16.1, page 534). In general for an ideal gas the formula for the speed of sound is.
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.
• The speed of sound increases with temperature. Would the distance between nodes increase or decrease if the temperature is increased. • The speed of sound is 1482 m/s in water. For a 512 Hz wave, what is the wavelength? 39
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. Sound, like all waves, travels at a certain speed and has the properties of frequency and 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. Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength.
approximate expression for the speed of sound in air versus temperature is V = 343 m/s + 0.6 (T –20 C). The speed of sound in air at 20 C is very nearly 343 m/sec and increases (decreases) by 0.6 m/sec for every degree above (below) 20 C. One can understand the dependence of the velocity of sound also from a microscopic point of view.
