Two wave pulses are moving toward each other, as shown in the figure. Pulse 1 moves at a speed of v1 = 0.23 m/s to the left, while pulse 2 moves to the right at a speed of v2 = 0.33 m/s. Their initial peak-to-peak separation is d = 4.78 m. 1. If the amplitude of pulse 1 is A1 = 3.4 cm and that of pulse 2 is A2 = 1.86 cm, what is the amplitude, in centimeters, after the elapse of time interval Δt when the two pulses meet? 2. Using the amplitudes A1 = 3.4 cm and A2 = 1.86 cm, what would be the amplitude, in centimeters, after the elapse of time interval Δt (when they meet) if pulse 2 were inverted?
