If you were to fling a spring you and see the wave passing through it, how would you measure the wavelength, the speed, the amplitude, etc.
Cause what I'm thinking is, you can't cause your only observing what is happening, you have no accurate answer even if you were to use a metre stick and stop watch, but my textbook is saying YOU CAN and is telling me to write a lab on it. How am I suppose to write a procedure where you can actually record the quantitative and the qualitative observation?
Hope that is more clear -0-
