(1) Find the angle between the first minima for the two sodium vapor lines, which have wavelengths of 589.1 and 589.6 nm, when they fall upon a single slit of width 2.40 µm.
(2) What is the distance between these minima if the diffraction pattern falls on a flat screen 1.40 m from the slit?
(3) Discuss the ease or difficulty of measuring such a distance. (Select all that apply.)
(a) This distance is easily measured using a microscope.(b) This distance is easily measured using a magnifying glass.(c) This distance is easily measured by the human eye.
