1 Two pulses on a string approach each other at speeds of 1 m/s
Two pulses on a string approach each other at speeds of 1 m/s. What is the shape of the string at t = 6 s? IG20.1

2 Two pulses on a string approach each other at speeds of 1 m/s
Two pulses on a string approach each other at speeds of 1 m/s. What is the shape of the string at t = 6 s? IG20.1

3 Move speaker 1 backward (to the left) 0.5 m.
Two loudspeakers emit waves with l = 2.0 m. Speaker 2 is 1.0 m in front of speaker 1. What, if anything, must be done to cause constructive interference between the two waves? Move speaker 1 backward (to the left) 0.5 m. Move speaker 1 backward (to the left) 1.0 m. Move speaker 1 forward (to the right) 1.0 m. Move speaker 1 forward (to the right) 0.5 m. Nothing. The situation shown already causes constructive interference. STT21.4

5 The interference at point C in the figure at the right is
maximum constructive. destructive, but not perfect. constructive, but less than maximum. there is no interference at point C. perfect destructive. STT21.5

6 The interference at point C in the figure at the right is
maximum constructive. destructive, but not perfect. constructive, but less than maximum. there is no interference at point C. perfect destructive. STT21.5

7 These two loudspeakers are in phase
These two loudspeakers are in phase. They emit equal-amplitude sound waves with a wavelength of 1.0 m. At the point indicated, is the interference maximum constructive, perfect destructive or something in between? STT21.6 maximum constructive perfect destructive something in between
