X.Drag the tape measure onto your window and use it to measure the wavelength.
XI.Press plate resume the wave.
XIl.Drag the timer onto your window and use it to measure the period.*Count the number of cycles in a chosen amount of time.*The more seconds you run the timer for while counting, the more accurate your frequency calculation will be.*You may toggle between "normal" and "slow" speed to count more cyclesin less time.*Divide the number of cycles you counted by the amount of time in step 1to determine the number of cycles per millisecond.*Convert your units to Hz or cyeles per second.
