A wave represented by the equation y = a cos(kx - t) is superposed with another wave to form a stationary wave such that the point x = 0 is a node. The equation for the other wave is:


  • (A):a sin (kx + t)
  • (B):

    - a cos (kx - t)

  • (C):- a cos (kx +t)
  • (D):- a sin (kx - t)

Best Answer

Correct Answer:

(C): - a cos (kx +t)
