In an interference experiment a laser light shines through a a double slit with separation 30 μ/m. The resulting pattern is created on a screen located a distance 1. 2 m from the aperture. Note that the color in the image does not necessarily correspond to the color of the laser light. The distance A is measured to be 34. 5 cm, and the distance B is 27. 6 cm. You may assume that the angles in this configuration are very small.
a. Find the wavelength of the laser light in nm.
b. What is the width of each slit in micron?
