1. Homework Statement
You send a pulse down a string that is attached to second string of unknown properties. the pulse returns to inverted and with a smaller amplitude.
A)is the speed slower or faster in the second string
B)is the wavelength smaller or larger in the second string
2. Homework Equations

3. The Attempt at a Solution
