A 2.0 m long string vibrates at its second harmonic frequency with a maximum amplitude of 2.0cm. One end of the string is at x = 0cm. Find the oscillation amplitude at x = 10,20,30,40, and 50cm.

2. Relevant equations

A(x) = 2asin(kx)

k= 2pi/wavelength

3. The attempt at a solution

I tried plugging the numbers into the equatio, but couldn't get the right answer. Can someone get me on the right track?
