The colors of the diffracted beams roughly match the wavelengths of those beams. Students can change the angle of the incident beam and the grating ruling density. Grat2 is a stationary grating with incident white light, used to demonstrate the relationship between the first and second orders of diffraction. Six visible colors of diffracted light shown in the first and second orders, plus the zeroth order reflection shown as a gray line. The colors of the diffracted beams roughly match the wavelengths of those beams.
Students can change the angle of the incident beam and the grating ruling density.
Diffraction in the zeroth, first, and second orders are shown. Students can change the angle of incidence, the wavelength of the incident light beam, and the grating ruling density. Diffraction in the zeroth, first, and second orders are shown. Students can change the angle of rotation of the grating, the angle between the incident beam and observed diffracted beans, the wavelength of the incident light beam, and the grating ruling density.
