Diffraction spectrometer using CD with CFL lamp (Working Model)

The Diffraction of Light Using CD Grating experiment is a simple and effective demonstration of light diffraction and the wave nature of light. This setup utilizes a CD as a diffraction grating, allowing students to observe the splitting of white light into its component colors. The experiment is designed for science classrooms, physics labs, and optical studies, providing hands-on learning about the principles of diffraction and interference.

Working Principle

Diffraction occurs when light waves bend around obstacles or pass through small openings, producing an interference pattern. In this experiment, a CD acts as a diffraction grating due to its microscopic spiral grooves, which scatter white light into its spectral colors.
