8) (5 pts) Surface waves are generated from two coherent sources, 51 and $2, separated by a small distance. The figure shows the crests (solid) and troughs (dashed) of the waves from $1 and $2 at an instant. Consider multiple oscillations of the sources. At which points are the oscillations of the water surface close to maximum? Assume that the amplitude of the waves from each source do not depend on distance. A. PointA only B. Point B only C. Point C only D. Point D only E. Points C and D
