We are familiar with the formula velocity = `sqrt(("elastic property")/("density"))` Can you guess the elastic property and hence the velocity of sound waves in a rod having density `rho` and force constant k?

Text Solution

Verified by Experts

Elastic property
`Y=(F/A)/(((Delta l)/(l)))=(K Delta l)/(A)xx(l)/(Delta l)=(Kl)/(A)`
`implies v=sqrt((Kl)/(A rho))`
