Interview response of an “A” student
Okay. Over a long, taut spring, the friction or the loss of energy should not be significant; so the wave should be pretty much the exact same height, distance -- everything. So, it should be about the same wave.
No, wait. Okay... “the displacement of (READING) ... is given by”...looking at the function of y ... Let's see...I guess it'll be a lot smaller than the wave I drew, because the first time -- x is zero, because e raised to the zero's going to be 1.... And then as x increases, ... e raised to the negative... So, if x keeps on getting bigger, e raised to the negative of that is going to keep on getting smaller. So the -- So the actual function's going to be a lot smaller
