A beam of green light is made to pass through two slits that are 5.0 x 10−3 meters apart. On a screen 4.0 meters away from the slits, an interference pattern appears with bands of light separated by 4.2 x 10−4 meters. What is the wavelength of the light?
A. 3.6 * 10^-8 m
B. 5.9 * 10^-7 m
C. 5.3 * 10^-7 m
D. 3.9 * 10^-6 m
