Apiece of steel string is under tension.
(a) If the tension doubles, the transverse wave speed (1) doubles, (2) halves, (3) increases by √2, (4) decreases by √2. Why?
(b) If the linear mass density of a 10.0-m length of string is and it is under a tension of 9.00 N, what is the transverse wave speed in the string?
(c) What are its waves’ natural frequencies?
