Question

u Review | Constants Part C An interference pattem is produced by light with a wavelength 600 nm from a distant source incident on two identical parallel slits separated by a distance (between centers) of 0.530 inm. Let the slits have a width 0.360 min. In terms of the intensity In at the center of the central maximum, what is the intensity at the angular position of 0,7 Enter your answer numerically. ΡΙ ΑΣφ ? I.9999 10 Submit Previous Answers Request Answer * Incorrect; Try Again; 5 attempts remaining Your answer seems to indicate that the intensity at a point on the screen does not depend on the single-slit diffraction pattern. Note that the pattern on the screen is due to a combination of single-slit diffraction and double-slit interference. Part D What is the intensity at the angular position of 0,? Enter your answer numerically.
