Three physics faculty members sit in three different cars at a railroad crossing. Three trains go by at different (constant) speeds, each emitting the same sound. Each faculty member uses a cell phone to record the sound of a different train. On the next day, during a faculty meeting, they plot the frequency as a function of time on a computer,resulting in the plots shown in the figure. Which of the three trains had the highest speed?
a) the one represented by the solid line
b) the one represented by the dashed line
c) the one represented by the dotted line
d) impossible to tell
