Question

Find the speed of a transverse wave on a 75-cm length of a cord when the tension in the cord is 320 N. The mass of the cord is 120 g.

Answer 1

Answer:

The speed of transverse wave will be 28.2842 m/sec  

Explanation:

We have given length of the card = 75 cm = 0.75 m

Tension on the card = 320 N

Mass of the card = 120 gram = 0.12 kg

So linear density $=\frac{mass}{length}=\frac{0.12}{0.75}=0.4kg/m$

We have to find the speed of the transverse wave

Speed is given by $v=\sqrt{\frac{T}{linear\ density}}$

$v=\sqrt{\frac{320}{0.4}}=28.2842m/sec$

So the speed of transverse wave will be 28.2842 m/sec
