Question

Velocity of transverse waves in strings is given by the formula $v=\frac{T}{\mu }$, where T and $\mu$ are respectively

• A. Time period, coefficient of friction
• B. Tension, mass
• C. Tension, mass per unit length
• D. Time period, mass per unit length

Answer 1

Answer: (C)

Tension, mass per unit length

As for the formula $v=\frac{T}{\mu }$

$T=$ Tension of the ring which is the key factor making the disturbance propagate along the string.

$\mu =$ mass per unit length as because mass gives rise to kinetic energy. If no mass then no kinetic energy.

Thus velocity of transverse waves $=\frac{Tension}{Massperunitlength}$
