Quizplus · Accepted Answer

The speed of a wave in a string is given by the formula v = sqrt(T/μ), where T is the tension in the string and μ is the linear mass density of the string. If we increase the tension in the string by a factor of 4, the speed of the wave in the string will increase by a factor of sqrt(4) = 2. Therefore, the correct answer is C.

You Increase the Tension in a String to Four Times
