Consider a Gaussian wave pulse with amplitude 1 cm travelling on a 4 m long string with two free ends, as shown. If the wave travels at 1 m/s, then what is the displacement y at x = 4 m and t = 2 s? Make sure you can explain your reasoning in terms of the physics of wave reflections and superposition. y (cm) t =0 s 0 I(m) 3 Answer: Submit All Answers
