Homework Statement
I know that the light wave must travel 17.3 km or 17300 meters.
I found experimentally that the frequency should be 2200 Hz. I picked it from a pool ranging from 0 Hz to 5600 Hz. The goal was to see what frequency was required to get the light to pass correctly through a gap in a wheel.
I am asked to use the data gathered to calculate "your speed of light."
Homework Equations
speed of light = wavelength * frequency
c = (lambda)*f
The Attempt at a Solution
I am assuming it is supposed to be around the actual speed of light which is 2.99x10^8 m/s. I am getting a value of 3.806x10^7 m/s by multiplying 17300 m by 2200 Hz.
Am I using the wrong values? Is there some constant I am overlooking that I need to throw in? Is there another equation?
