Physics Practical Fsc I Vibrograph Frequency of AC Supply

Physics Practical Fsc I | Vibrograph | Frequency of AC Supply

Object:

To determine the frequency of A.C supply using a vibrograph (Melde's apparatus). Note down length of one loop (l) for your different masses suspended to the stretched string. Draw a graph of total mass suspended (M) and square of length of one loop (L square). Calculate frequency of AC supply. Also calculate percentage error.
