Consider a wave propagating in the negative x-direction with frequency f = 100 Hz. At t = 5 sec the displacement associated with the wave is given by
y(x, t = 5)= 0.5 cos(0.1 x) where x and y are measured in centimeters and t in seconds. Obtain the displacement y(x,t).
What are the wavelength λ and velocity y associated with this wave?
