Question

An image is produced on a screen from two narrow slits separated by a distance d. A second image is produced by two wide slits (a) separated by the same distance d which is equal to 5a. How does the intensity from the first image compare with the intensity of the second image? a. The intensity of the first and second image oscillates between bright (max) and dark (min) regions, but the first image has a decreasing maximum intensity as it gets further from the center while the second image's maximum intensity is constant between each fringe. b. The intensity of the first and second image is uniform from the center of the screen out. However, the second image will have more intensity in the center region. c. The intensity of the first and second image oscillates between bright (max) and dark (min) regions. These images produce the same interference pattern, but except the second image will have an overall greater intensity. d. The intensity of the first and second image oscillates between bright (max) and dark (min) regions, but the first image has a constant maximum intensity between each fringe while the second image's maximum intensity decreases as it gets further from the center. e. The diffraction patterns are independent and have no similarities or differences

Explanation / Answer

intensity is directly propotional to the square of the slit width. therefore the intensity in the second case will be more. therefore the correct option will be the option c
