Question:

The drawing shows a snapshot of a transverse wave traveling along a string at 10.0 m/s. The equation for the wave is y (x, t) = A cos ((t + kx). (a) Is the wave moving to the right or to the left? (b) What are the numerical values of A, (, and k? (c) At what times could this snapshot have been taken? (Give the three smallest nonnegative possibilities.)
