A long string is pulled so that the tension in it increases by a factor of four.If the change in length is negligible,by what factor does the wave speed change?
A) 0.25
B) 0.50
C) 2.0
D) 4.0

Question

Quizplus · Accepted Answer

The wave speed on a string is proportional to the square root of the tension. If the tension increases by a factor of four, the wave speed increases by a factor of the square root of four, which is 2.0.
