1. Chapter 38 Diffraction Patterns EXAMPLES

2. Chapter 38: Diffraction Patterns and Polarization: Examples

3. Example 38.1 Where Are the Dark Fringes? Light with = 580 nm reaches a slit with a = 0.3 mm. The viewing screen is at 2.0 m from the slit. Find: A) The position of the first dark fringes B) The width of the central bright fringe

4. Example 38.2 Eye Resolution ( A). Estimate  min for the human eye. Using a light of 500 nm and the daytime average diameter for a human pupil of 2.0 mm (B). Determine the minimum separation distance d between two point sources that the aye can distinguish if the point sources are a distance L = 25cm from the observer.

5. Example 38.3 Telescope Resolution The Keck telescope at Mauna Kea, Hawaii, has an affective diameter of 10 m. Find the resolution  min for 600-nm light
