1 Physics 1C Lecture 27C "You cannot trust your eyes if your imagination is out of focus." --Mark Twain Quiz 3 Info It will be a Scantron test that covers Chapters 24, 25, and 26. A list of equations, constants, and conversions will be provided on the quiz. You are to write the version of your test on the Scantron form. You will use the Quiz Code Number that you were assigned at the first Quiz. You are expected to abide by UC Policy on Integrity of Scholarship. Resolution If viewed through a slit of width, a , and applying Rayleigh’s criterion, the limiting angle of resolution is: For the images to be resolved, the angle subtended by the two sources at the slit must be greater than θ min . For a circular opening of diameter D : Resolution: Example Charon, the moon of Pluto, was discovered in 1978. On a photograph from an Earth- based telescope, Charon appears as a subtle bump on the edge of Pluto. On a Hubble Space Telescope photo (1994), Pluto and Charon are clearly resolved. Atmospheric turbulence smears the image on the 1978 photo. Diffraction Grating The diffraction grating consists of many equally spaced parallel slits. A typical grating contains several thousand lines per centimeter. You will again get an interference pattern that consists of bright and dark spots. The bright spots will be sharper than in the double slit case. Diffraction Grating
