Measuring speed of EM wave\ Equipment: Signal/Function Generator, Oscilloscope & Co-axial Cables\ The basics:\ Make an estimate of the uncertainty in the time measurements, and explain how you arrived at it. Think about the smallest divisions you can measure on the horizontal scale the oscilloscope screen. Make sure to record this time as

time_(m)u_(t)

where

u_(t)

is the funcertainty in the measurement. (Guess the value of from the oscilloscope's screenshot)\ Now find the length of the long cable and

4.57m

, which should be marked on a white tag on each cable bundle. Include an estimate of the uncertainty in this length 0.5 cm). You should take this into account in the length measurement and uncertainty estimation as well. Don't forget to convert them to meters.
