WebMar 11, 2024 · This is called a diffraction grating. Figure 2.6. 2: .17: Intensity of interference pattern from a diffraction grating with 2 slits on the screen in figure 2.16. The position x on the screen is proportional to the angle θ in the small angle approximation. Figure 2.6. 2: .18: Intensity of interference pattern from a diffraction grating with 4 ... WebThe analysis of a diffraction grating is very similar to that for a double slit (see Figure 27.19).As we know from our discussion of double slits in Young's Double Slit Experiment, light is diffracted by each slit and spreads out after passing through.Rays traveling in the same direction (at an angle θ θ relative to the incident direction) are shown in the figure. irish moss ground cover seeds
