Chapter 18, Problem 2(choose chapter or problem)
A string of length L,mass per unit length m,and tension T is vibratingat its fundamentalfrequency. (i) If thelength of the string isdoubled, with all otherfactors held constant, what is the effect on the fundamentalfrequency? (a) It becomes two times larger. (b) Itbecomes !2 times larger. (c) It is unchanged. (d) Itbecomes 1/!2 times as large. (e) It becomes one-halfas large. (ii) If the mass per unit length is doubled,with all other factors held constant, what is the effecton the fundamental frequency? Choose from the samepossibilities as in part (i). (iii) If the tension is doubled,with all other factors held constant, what is the effecton the fundamental frequency? Choose from the samepossibilities as in part (i).
