You (a detective) have detected a potential case of interference of two travelling waves. A witness comes forward and presents you with some evidence - a snapshot graph of the resulting interference pattern taken at a time, t = 0 s (shown below). A second witness informs you that both travelling waves were seen moving in the same direction, to the left, with a velocity of 2 m/s. A third witness confirms that one ofthe two travelling waves had a phase constant ((1)1) of % and that the two travelling waves had the same amplitude and wavelength. b) D(x, t = O s) (m) 0 0 0.5 1 1.5 2 2.5 3 x (m) (0.5 pt) What are the wavelength and frequency {f} of the two travelling waves that produced the interference pattern shown above? (2 pts) What is the phase constant ofthe second travelling wave ((I)2)? [Hintz How does the phase constant of the interference pattern of two waves travelling in the same direction depend on the phase constants of the original travelling waves?]. Note when reading values off the graph you can round to l 4 . What is the amplitude of the two travelling waves that produced this interference? Round your answer the nearest 0.1m. Round your final answer to the nearest integer multiple of to the nearest integer
