In a In a Youngs double-slit experiment, a set of pa ts with a separation of 0.136 mm is illuminated by light having a wavelength of 551 nm and the interference pattern observed on a screen 3.50 m from the slits. (a) what is the difference in path lengths from the two suits to the location of a second order bright fringe on the screen? (b) What is the difference in path lengths from the two slits to the location of the second dark fringe on the screen, away from the center of the pattern? Hm Need Help? LReadN

    As an admirer of Thomas Young, you perform a double-slit experiment in his honor. You set your slits 1.25 mm apart and position your screen 3.83 m from the slits. While Young had to struggle to achieve a monochromatic light beam of sufficient intensity, you simply turn on a laser with a wavelength of 631 nm. How far on the screen are the first bright fringe and the second dark fringe from the central bright fringe? Express your answers in...
