Waves are traveling on a uniform string under tension. For each of the following changes, is the wave speed increased, decreased, or unchanged? Indicate your answers with “I” for increased, “D” for decreased, or “U” for unchanged. (a) The string tension is doubled while its mass and length are constant. (b) The string is folded in half and the tension is constant. (c) The string is cut to half its original length and the tension is constant. (d) The string is cut to half its original length and the tension is doubled.
