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

The speed of transverse wave will be 28.2842 m/sec

Step-by-step 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
`=(mass)/(length)=(0.12)/(0.75)=0.4kg/m`

We have to find the speed of the transverse wave

Speed is given by
`v=\sqrt{(T)/(linear\ density)}`

`v=\sqrt{(320)/(0.4)}=28.2842m/sec`

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