A harmoni wave in a wire has amplitude 6.32mm, wavelength 2.99m, and frequency 157Hz. The wire has linear mass density of 11 g/m. Determine the wire's tension.

Find the wave speed.

You have already been given the mass-per-unit length, so it shouldn't be hard to plug this and your wavespeed into an equation to find the tension in the wire.

Your 3 first values should be used to find the wave speed.

Need any more help just ask and I'll give you an equation to use.
