A 120-cm-long, 3.0 g string oscillates in its n = 4 mode with a frequency of 150 Hz and a maximum amplitude of 5.5 mm. Wavelength is 0.6 m.

What is the tension in the string?

2. Relevant equations

f = sqrt(TL/m)/2L

3. The attempt at a solution

150 = sqrt(1.2T/.003)/2.4

Solving for T gives me

T = 324

Which, according to the program(Mastering Physics), is wrong. I'm not sure if this is the right equation, but its the only found I could find that uses all of the information I have, excluding amplitude.
