A laser has a wavelength of 644 nm. A grating and a lens are used to split the beam into three parallel beams spaced 1.85 cm apart. What is the maximal value of the slit spacing so that the grating produces three and only three beams? What is the minimal value of the slit spacing so that the grating produces three and only three beams? If the slit spacing is 1.00 μm, what focal length lens should be used?
