In which of the following media will a wave propagate at the largest speed?
A) A loose, light rope.
B) A loose, heavy rope.
C) A tight, light rope.
D) A tight, heavy rope.

Question

Quizplus · Accepted Answer

The speed of a wave in a rope is determined by the tension in the rope and its mass per unit length. A tight rope has more tension, and a light rope has less mass per unit length, both of which contribute to a higher wave speed. Therefore, a tight, light rope (C) will allow a wave to propagate at the largest speed.
