Question

10.23) An opaque screen contains a rectangular hole 0.199 mm (along the z-axis) by 0.100 mm (along the y-axis). It is illuminated by light at 543 nm from a helium-neon laser. A big positive lens with a 1.00-m focal length forms a Fraunhofer pattern on its focal plane. Lo- cate the first minima along the Y- and Z-axes.
