Part A: For light wavelength lambdha=650 nm = 6.50*10^-7 m passing through a slit of a = 0.08mm, what are the angles that give us the first three minima in a diffraction pattern?
Part B: For the same wavelength, but passing through a double slit set up where the slits are d= 0.50nm apart, find the angles for the first three minima and the first three maxima.
