# Physics

A string on a musical instrument (1 m long) carries travelling waves at 100 m/s.

What are the three lowest notes that this string can play (keeping the string at its full length)?

You have the length. You can put one half wavelength on the string, one wavelength, or 3/2 wavelength.

Use the wave equation to determine frequency.

Check my thinking.

What is the wave equation?
