To Determine the Wavelength of Diode Laser using Diffraction Grating for Physics Lab Experiments

Wavelength of Laser Experiment is an optical setup designed to understand the working principles of diffraction grating and single slit. The setup is used to determine the wavelength of laser light by observing the diffraction pattern.

The laser is used as a monochromatic light source, while the diffraction grating or single slit produces a diffraction pattern. Interference and diffraction are important phenomena that demonstrate the wave nature of light. A diffraction grating consists of numerous narrow and closely spaced parallel slits and can be used to determine the wavelength of intense monochromatic light.
