Question
1. There should be intensity Io from a single slit 0.04mm. In ideal conditions, as the number of slits (N) is increased, the diffraction pattern intensity (I) should increase by I=N2Io. Fill out the bottom row of table 1 using this equation. Does this row have a constant value? Why or why Not?
2. Consider a diffraction screen with 3 slits. What would be the purpose of using a diffraction screen with 10 slits? Give at least 2 reasons.
Slits(N) 2 3 4 5 Intensity (I) 0.035 0.065 0.099 0.113 Io (I / N2) 0.00875 0.007222 0.006188 0.00452Explanation / Answer
1. It doesnt have the same value as each slit is at some distance from the other. This causes only a portion of the Intensity from each is added.
2. Context is required to answer this.
