For an aperture of width 1mm and using light of wavelength of 633 nm, estimate the distance from the aperture at which the Faunhofer approximation would be appropriate.
a. Under the Fraunhofer condition, what would be the angle of the first minimum?
b. If the screen is 1m away, how far from the central maximum would the first minimum be located?
