The diffraction grating experiment using a Helium-Neon (He-Ne) laser is a classic optical physics experiment that provides a precise method for measuring the wavelength of coherent light and validating the wave nature of light through diffraction and interference. The He-Ne laser, with its well-defined wavelength (typically 632.8 nm), serves as an ideal monochromatic light source for producing clear and stable interference patterns. This experiment is fundamental in laser optics and instrumentation, offering practical insight into spatial coherence, grating theory, and precision measurement.
