RUBBER HAMMER This experiment is about where we verify the second law of tension using sonometer. The second law of tension states that the frequency of vibration (f) of a stretched string is directly proportional to the square root of its tension (T), provided the resonating length (l) and mass per unit length (m) remain constant f is directly proportional to square root of T.
It works on the phenomenon of resonance and transverse stationary waves.
The fundamental frequency of the vibrating string length matches the frequency of an external sounding body like a tuning fork.
The frequency of vibrational string can be calculated with the given formula.
