A pulse traveling along a string of linear mass density m
Chapter 16, Problem 61(choose chapter or problem)
A pulse traveling along a string of linear mass density m is described by the wave function y 5 [A0e2bx] sin (kx 2 vt) where the factor in brackets is said to be the amplitude. (a) What is the power P(x) carried by this wave at a point x? (b) What is the power P(0) carried by this wave at the origin? (c) Compute the ratio P(x)/P(0).
