Question

re-La b #ll:Diffraction Name: Section: M T WR 2P 5P 1. Light from a red laser passes through a sing increased by a factor of two, what e: Assume that the angle θ is suffi a sit to form a diffraction pattern. If the width of the slit the central maximum? ientlysniall solat (sine, is nearly eq (a) The width of the central maximum increases by a factor of 4 (b) The width of the central maximum decreases by a factor of 4 (c) The width of the central maximum decreases by a factor of 4 (d) The width of the central maximum increases by a factor of 2 (e) The width of the central maximum does not change. 2. The table lists the range of wavelengths in vacuum corresponding to a given color. Which one of these colors will produce a diffraction pattern with the widest central maximum, assuming all other factors are equal? 780 622 622 597 597-577 577-492 492 -455 455 -390 orange yellow blue violet (d) blue (e) violet (a) red (b) yellow (c) green
