A transverse wave has a frequency of f = 26 Hz and a wavelength of λ = 11 m. The wave obtains a maximum displacement of ym = 2.2 m and propagates in the -x direction.
(a) Given the form y(x,t) = A sin(B) for the displacement of the wave, input an expression for A.
(b) Using the same form y(x,t) input an expression for B.
(c) How fast is the wave traveling in m/s?
