Two strings 1 and 2 are taut between two...

Two strings 1 and 2 are taut between two fixed supports (as shown in figure) such that the tension in both strings is same. Mass per unit length of 2 is more than that of 1. Explain which string is denser for a transverse travelling wave.
.

Text Solution

Verified by Experts

The correct Answer is:
A
Speed of a transverse wave on a string
`v=sqrt(T/mu)` or `v prop 1/(sqrt (mu))`
Now, `mu_2 gt mu_1`
` :. v_2 ltv_1`
i.e. medium 2 is denser and medium 1 is rarer.
