2. Double-slit patternA screen is placed a distance R = 10m away from a 2-slit setup.The distance between slits is d = 0.1mm. A laser beam isincident on the slits from the left, as shown.The intensity of the central maximum is I=1 W/m²Point P, located 180 mm above the central maximum, marks thelocation in the interference pattern of the third bright fringe.(a) [2 points] Calculate the wavelength of the laser.If we instead look at a point Q on the screen 140 mm from the central max:(b) [3 points] Determine the path difference between both rays at point Q. Do the waves interfereconstructively, destructively or neither at point Q?9:08 AM4/30/2021
