Question
A standing wave has the following wave-function: y(x,t) = 0.2 sin(3Ttx) cos(12t),
%3D
where x and y are in meters, and t is in seconds. If the length of the string is L = 2
m and it is fixed at both ends, then the harmonic, n, in which the string is
vibrating is:
O n= 3
9 = u O

A standing wave on a stretched string fixed at both ends is described by: y(x,t) =
0.1 sin(2rtx) cos(100Ttt). The string has a length L = 1 m. For t> 0, an element on
the string located at x = 0.75 cm would have a zero speed for the second time at:
O t= 0.01 sec
O t= 0.025 sec
O t= 0.015 sec
O t-0.005 sec
O t= 0.02 sec
