Diffraction Experiment Concepts

The video tutorial demonstrates a laser diffraction experiment using a diffraction grating. It covers setting up the equipment, aligning the laser, and measuring the diffraction spread with a ruler. The tutorial also explains how to calculate diffraction angles using trigonometry and explores different diffraction gratings. The video concludes with a preview of the next experiment involving CDs and DVDs.
