WebUnlike a simple prism, a diffraction grating generally produces multiple output beams according to different diffraction orders.. An important question is how the output power is distributed over the different diffraction orders. In other words, the diffraction efficiency for certain diffraction orders is of interest. This depends on the shape of the wavelength … WebSep 12, 2024 · One example of a diffraction pattern on the screen is shown in Figure 4.4.1. The solid line with multiple peaks of various heights is the intensity observed on the screen. It is a product of the interference pattern of waves from separate slits and the diffraction of waves from within one slit. Figure 4.4.1: Diffraction from a double slit.
