16. Light from a coherent, monochromatic source shines through a double slit onto a screen 5 meters away. The slits are 0.18 mm apart. The dark bands on the screen are measured to be 1.7 cm apart. a) What is the wavelength of the incident light? Report you answer in Ångstroms, recall 1A = 10-10 meters. b) At what angle away from the central maximum does the first bright fringe occur? State your answer in degrees, not radians Make sure to set your calculator to degrees.
