I did an experiment involving the speed of sound at different temperatures. I placed two microphones at a fixed distance apart and I measured the time taken for a sound wave to travel between the two mics. I repeated this for different temperatures. I want to make a graph for my results, but I want a straight line relationship.
v=d/t , v = 331 + 0.6T
The Attempt at a Solution
I could manually work out speed using v=d/t and plot v against the Temperature, T. However I do not know if this will give me a straight line. Or I can also plot the time against the temperature.
Extra question: in both cases, will the gradient be of any use to me?
