Two waves travel simultaneously through the same medium.
 
  The first wave is described by y1(x,t) = Acos(kx-t) and the second wave by y2(x,t) = A cos(kx-t + ). If the amplitude of the resulting superposition is A/2, what are the possible values of ?
  A)
 
  /6, -/6
 
  B)
 
  /3, -/3
 
  C)
 
  /8, -/8
 
  D)
 
  60, -60
 
  E)
 
  /4, -/4

  3.7 A
  B)
 
  42 A
