In a lecture demonstration, laser light is used to illuminatetwo slits separated by 0.5 mm, and the interference pattern isobserved on a screen 4.0 m away. The distance on the screenfrom the centerline to the, m = 16 bright fringe is 6.0 cm.
a. What is the wavelength of the light?
b. What is the distance from the centerline to the, m = 10 dark fringe?
