Question:

Look at the Young€™s Experiment depicted in Fig. 9.10. Thermal quasimonochromatic light, filtered to a mean of 500 nm, impinges from the left on the 0.10-mm-diameter hole in the source screen. Roughly how far apart at most will the two pinhole apertures be if fringes are to start being observed? The source is 1.0 m from the aperture screen.
