Wave in stretched string

Answer 1

Wave Stretch Exercise was developed in 2005 to help to create flexible body and mind. ... Ideal for daily body care, since Zen Ring (Wave Stretch Ring) 's curved arch shape fits perfectly to the body's natural curvature. It relieves muscle stiffness, improves blood flow, it is an effective tool to recover from fatigue.

Answer 2

The speed of waves in a stretched string depends on the tension F in the string as well as the mass per unit length μ of the string as explained below:

For such a string, the fundamental frequency would be Hz.

The more a string is stretched, the faster waves travel in it.

The formula that relates tension F in the string and the waves speed v is:

V= √F/μ (where μ= M/L is mass per unit length of the string).
