Question

A string is 50.0 cm long and has a mass of 3.00 g. A wave travels at 5.00 m/s along this string. A second string has the same length, but half the mass of the first. If the two strings are under the same tension, what is the speed of a wave along the second string?

Answer 1

$v\sim\lambda\sim l,$

$v_2=\frac{v_1}2=2 .5~\frac ms.$
