# The second resonance of string? [closed]

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?

This question appears to be off-topic. The users who voted to close gave this specific reason:

• "Homework-like questions should ask about a specific physics concept and show some effort to work through the problem. We want our questions to be useful to the broader community, and to future users.

• 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 $2\:\mathrm{cm}$.
