second. So the frequency is the reciprocal of the period‚ and the period is the reciprocal of the frequency. We will calculate the frequency using formula Frequency(f)=number of dots/ time‚ and then calculate the period using formula Period(T)= per unit time/ frequency. Procedure: 1. Follow instructions and assemble the apparatus. 1. Put a carbon paper disc which is carbon-side-up on the fix shaft between the gates. 2. Place a short strip of timer tape in the recording timer over the paper disc
