Question

The speed of a transverse wave in an elastic string is v₀. If the tension in the string is reduced to half, then the speed of the wave is given by –

• A. $\frac{v_{0}}{\sqrt{2}}$
• B. $v_{0}\sqrt{2}$
• C. $\frac{v_{0}}{2}$
• D. 2 v₀

Answer 1

Answer: (A)

$\frac{v_{0}}{\sqrt{2}}$

Answer 2

v = $\sqrt{\frac{T}{\mu}}$
