Question
Consider transverse waves on a wire string, with the changes listed below. Answer `true' (T), `false' (F), or `cannot tell' (C) to each of the five statements. E.g., if the answer to the first statement is T and to the rest, F, enter TFFFF. 1If the tension is increased and the mass of the wire is decreased (assuming the length remains the same), then the wave speed decreases.
2 If the length of the wire increases by a factor of 2 and the tension and mass remain the same, the speed of the transverse wave decreases by a factor of square root of 2.
3 If the tension in the wire is doubled, the speed of the transverse wave increases by a factor of square root of 2.
4 If the mass of the wire is doubled and the tension and length remain the same, the speed of the transverse wave decreases by a factor of 2.
5 If the tension is decreased and the mass of the wire is decreased (assuming the length remains the same), then the wave speed increases.
