Quizplus · Accepted Answer

According to the formula for wave speed on a stretched string, v = sqrt(T/u), where T is tension and u is linear density. As tension increases, wave speed should also increase. Curve B shows a steady increase in wave speed with increasing tension, while the other curves show either no change or erratic changes in wave speed.
