1. The problem statement, all variables and given/known data The equation describing a transverse wave on a string is y(x,t) = (3.50mm)sin[(t/162s) - (x/42.5)] Find the transverse displacement of a point on the string when t = 0.220 s and at a position x = 0.140m 2. Relevant equations y(x,t) = Asin(wt-kx) or y(x,t) = Asin2pi[(t/T)-(x/wavelength)] k = 2pi/wavelength w = 2pif 3. The attempt at a solution I know from previous parts of the problem that I got right: wavelength = 0.148m f = 1/T = 25.8 Hz A = 3.5mm I thought that you would just plug the values of t and x into the second equation I gave, but it was wrong. I keep on coming up with y = 1.73, no matter what I do, but the answer is y = -3,46. What am I doing wrong?
