# The second resonance of string?

What is the relationship between "the second resonance " and string and the wavelength. Like in this question: if the length of the string is 2cm with second resonance, then what is wavelength?

You know about (speed)=(wavelength)*(frequency) and that the wave speed is constant if the tension is constant. –  ja72 May 13 '13 at 19:06

If your string length is $2\:\mathrm{cm}$ then the wavelength of the first vibrational harmonic is $4\:\mathrm{cm}$. The second vibrational mode has a wavelength of $2\:\mathrm{cm}$.
