1. For light of wavelength 650 nm = 6.50 * 10^-7 m passing through a slit of a = 0.08 mm, what are the angles that give us the first three minima in a diffraction pattern?

2. For the same wavelength, but passing through a double-slit setup where the slits are d = 0.50 mm apart, find the angles for the first three minima and the first three maxima.
