                                Speed of Sound



1. A common way to measure the distance to lightning is to start counting, one count per
second, as soon as you see the flash. Stop counting when you hear the thunder and divide
by five to get the distance in miles. Use this information to estimate the speed of sound in
m/s.




2. Why do the procedures call for a measurement of the ambient (room) temperature
prior to measuring the speed of sound?




 3. Does a sketch of a graph that recreates the computer screen display need to be
performed on graph paper?




4. Does a graph that is created from a data table need to be performed on graph paper?
