55965 Measurement of Wavelength of LASER is an Optical Setup to Understand the working of Diffraction Grating and Single Slit. It determines the wavelength of LASER Light. Here the LASER is used as a Monochromatic light source and a Diffraction grating/Single Slit for getting a diffraction pattern. Interference and Diffraction are the two main phenomenon which demonstrates the wave nature o f light. Diffraction grating allows a beam of light to resolve into different colours. It usually consists of thousands of narrow, closely spaced parallel slits. With the help of this setup we can find the wavelength of any intense Monochromatic light.
