Sound Wave Problem

  1. May 20, 2007 #1
    1. A soldier hears the sound of the firing of a distant cannon 6.00 seconds after seeing the flash. If the temperature is 20 degrees Celsius, how far is the soldier from the flash?

    2. D = R * T

    3. Since the speed of sound at 0 degrees Celsius is 330 m/s, the speed of sound at 20 degrees Celsius is 342 m/s.
    With that being said, how do you find the distance? D = 342 * 6 ?

    The only thing that could make this hard is if you wanted to take light into account. It takes some time for light to reach the soldier first, but its almost instant and makes no significant difference
