Sketch intensity as a function of position along a line across the center of the hole in the plane of the hole. 6) Red light is normally incident on round hole of diameter 10-5 m. Sketch what you think the intensity pattern looks like as a function of position on a screen 1 m distant. Sketch intensity as a function of position along a line through the center of the pattern on the screen. 7) Red light is normally incident on round hole of diameter 10-5 m. Sketch what you observe on the screen ~10 m distant. Sketch intensity as a function of position along a line through the center of the pattern on the screen....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
