# Physics - Laws of Traverse Vibrations

**Laws of Traverse Vibrations**

The fundamental frequency of a stretched String fixed at both end is given by

**First Law or Law of Length :**

** **When the tension (T) and linear density (m) are constant, the frequency of Vibration (n) of a streched String vibrating in one segment is inversely proportional to its length (l)

**Second Law or Law of Tensions :**

** **When the length (l) and the linear density (m) are constant, the frequency of Vibration (n) of a streched String vibrating in one segment is inversely to the square root of the tension (T) in the wire

**Third Law or Law of Linear Densities :**

When the length (l) and Tension (T) are constant, the frequency of a streched string vibrating in one Segment is inversely proportional to square root of linear density.
