Problem 9 Two slits separated by a distance of d = 0.110 mm are located at a distance of D = 750. mm from a screen. The screen is oriented parallel to the plane of the slits. The slits are illuminated by a coherent light source with a wavelength of A = 527 x 10" mm. The interference pattern shows a peak at the center of the screen (m 0) and then alternating minima and maxima. a) What is the...
A laser beam is incident on two slits with separation d= 0.034 mm. A screen is placed L = 1.2 m from the slits. The wavelength of the laser light is i = 4500 A. 81 and 82 are the angles to the first and second bright fringes above the center of the screen. (a) Express sin(@) in terms of d and 1. (b) Express sin() in terms of d and 1. (c) Express the distance between the two bright...
1. Consider an arrangement of N rectangular slits with a distance d between adjacent slits. The slits emits light rays coherently and in phase at wavelength 4. The electric field at a distant point P is N-1 Ep(r, t) = [Eo cos (kr - wt +no), TO where Eo is the amplitude at P of the electric field due to an individual slit, o = 27d sin 0/X, is the angle of the rays reaching P (as measured from the...

Two parallel slits are illuminated by light composed of two wavelengths. One wavelength is AA-572nm. The other wavelength is Ag and is unknown. On a viewing screen, the light with wavelength 1-572nm produces its third-order bright fringe at the same place where the light with wavelength As produces its fourth dark fringe. The fringes are counted relative to the central or zeroth-order bright fringe. What is the unknown wavelength? Number i Units

4. This problem deals with Jones calculus. An optical rotator is a polarization element that rotates the linear polarization state of an incident field by an angle φ. The Jones matrix for an optical rotator can be given like so cosφ sin φ -sin φ cos φ (a 1pt) Using the Jones calculus show that the linear polarization of a field initially polarized along the x-axis is rotated by the optical rotator. (b 1pt) Show that for an initial...
