PHYS-1200 PHYSICS II SPRING 2005 Post Quiz 15 Name___________ ANSWERS _________________ 1. y = (4.4 m) sin [(0.85 m -1 ) x – (1.5 s -1 ) t ] Which of the following waves will add with the above wave to produce sinusoidal standing waves? (Circle the correct answer.) y = (4.4 m) sin [(0.85 m -1 ) x + (1.5 s -1 ) t ] y = (4.4 m) sin [(0.85 m -1 ) x – (1.5 s -1 ) t ] y = (8.8 m) sin [(1.7 m -1 ) x – (1.5 s -1 ) t ] y = (4.4 m) cos [(1.7 m -1 ) x – (1.5 s -1 ) t ] y = (8.8 m) sin [(0.85 m -1 ) x – (1.5 s -1 ) t ] y = (8.8 m) sin [(0.85 m -1 ) x + (1.5 s -1 ) t ] y = (8.8 m) sin [(1.7 m -1 ) x + (1.5 s -1 ) t ]) 2.
