Slit-Diffraction Spectra

Slit-Diffraction Spectra


The aim of the experiment is to explore the basic features of diffraction and interference of light.
For this purpose data about diffraction patterns are collected using an optical bench where position and light intensity are measured by two sensors interfaced to a graphing calculator.
Experimental data are then compared to theoretical patterns calculated following Fraunhofer model of diffraction.
