(By a point source we mean a source of waves having linear dimensions small in comparison to the wavelength of the radiation.) The term $d$$\Delta r = r_2-r_1$$\Delta r = n\lambda$$\Delta r = d\sin\theta$$\theta_{max}$$n\lambda = d\sin\theta_{max} (\mathrm{for\;n = 0,1,2,\dots)}$$r = \left(n + \frac{1}{2}\right)\lambda$$\theta… text/html 2024-08-02T14:04:52+00:00 Anonymous (anonymous@undisclosed.example.com) https://physlab-wiki.com/phylabs/lab_courses/phys-120_130-wiki-home/spring-experiments/diffraction/setup?rev=1722621892&do=diff Diffraction ---------- Diffraction scanner * Optical rail * 3 post holders * Laser * Vernier diffraction slits in holder * Diffraction scanner * Lab Quest Mini * 2 analog to telecom wires * Meter stick Setup: * Make sure the laser works. (If it buzzes, it is dying and should be replaced.)
