(a) If y₁ = (2.50 cm)sin [(3.30 cm-¹)x-(1.85 s-¹)] and y₂ = (3.25 cm)sin [(2.25 cm-1)x+ (1.25 s-¹) represent two waves moving toward each other on a string, find the superposition of the two waves at x = 1.40 cm and t=2.45 s. X 356 The superposition of the two waves, is given by the sum of the two wave functions. Evaluate y, and y2 at the given location and time. cm (b) Now consider the same two waves on the same string. If they are both moving to the left instead of opposing directions, find the superposition of the waves at x = 1.40 cm and t = 2.45 s. (Assume the +x direction is to the right.) -1.78 How does a wave moving to the left differ from one that is moving to the right? cm Additional Materials Reading
