Harmonic Waves and Overtones

1. The problem statement, all variables and given/known data

A 2.00m long rope is stretched between two supports with a tension that makes the speed of transverse waves 48.0m/s .

What are the wavelength of the second overtone?

2. Relevant equations

L=nλ/2

3. The attempt at a solution

I got 2.00 m. Since L=2.00m and n=2 being the 2nd overtone. The site counted it wrong.

Edit: Also I did the same problem but with the 4th overtone using that equation and got it correct.
