Question

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 path length difference between the two waves from the two slits at the first (m = 1) maximum on the screen? Submit Answer Tries 0/6 b) What is the path length difference between the two waves from the two slits at the first (m 0) minimum on the screen? Submit Answer Tries 0/6 c) Calculate the distance on the screen between the central maximum (m = 0) and the first (m = 1) maximum (You can assume sin(0) tan(0) 0, with 0 expressed in radians) 23

Answer 1

at 1st moximum Ca path dift. between two waves Ax=d=527x106mm (6) 1st mininum I Da=1 = 263.5x10-6mm. (c) distance between central maximum & 1st maximum - 527x106mm x 750 mm - D 0.110mm = 3.59mm Any
