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.
KEY - Worksheet – Speed of Sound. 1. The speed of sound, like all waves, depends on the ___medium____ through which it travels. Sound travels fastest in __solids__ and slowest in ___gases___. 2. The speed of sound in air depends on the __temperature __ of the air.
air. The speed of sound can be determined at ANY temperature, T, by the equation. V: speed of sound (m/s) T : Temperature (degrees Celsius) Example 1: What would the speed of sound be on a 15 oC day? Example 2: Suppose you measure the speed of sound in air to be 348.8 m/s. What is the temperature of air? Example 3:
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.
