The figure is a snapshot graph of two plane waves passing through a region of space. Each wave has a 2.0mm amplitude and the same wavelength. What is the net displacement of the medium at points a, b and c?

Problem 1: The figure below shows four identical point sources of sound that are uniformly spaced on an x-axis. Sq d- d S3 d S4 P The sources emit sound at the same wavelength X and same amplitude A, and they emit in phase. A point P is shown on the x axis. Assume that as the sound waves travel to P, the decrease in their amplitude is negligible. What multiple of A is the amplitude of the net wave at P if distance d in the figure is (a) X/4, (b) A/2, and (c) X?

Two progressive waves y1=Asin(2πλx−ωt)y1=Asin⁡(2πλx−ωt) and y2=Asin(2πλx−ωt−π2)y2=Asin⁡(2πλx−ωt−π2) travel in the same direction. Calculate the velocity of the wave produced as a result of interference of these two waves. Take A=5A=5 cm, λ=λ=6.9 m and ω=ω=12.3 rad/s (radian per second). Give your answer in SI units.
