The figure shows the interference pattern that appears on a dis-tant screen when coherent light is incident on a mask with two identical, very narrow slits. Points P and Q are maxima; Point R is a minimum. The wavelength of the light that created the interference pattern is = 571nm, the two slites are separated by rm d = 6 m, and the distance from the slits to the center of the screen is L = 80cm . The difference in path length at a point on the screen is s = |s1 s2|, where s1 and s2 are the distances from each slit to the point. What is s (in nm) at Point P? Group of answer choices 0 -1 1 80
