Question

Monochromatic light passes through two parallel narrow slits and forms an interference pattern on a screen. As the distance between the two slits is decreased, the distance between light bands in the pattern on the screen will (5 points)A. decreaseB. increaseC. remain the sameAs an electromagnetic wave travels through a vacuum, the individual particles of the medium moveA.in ellipses B.in circles C.parallel to the direction of wave travelD. perpendicular to the direction of wave travel

Answer 1

When light passes through the slits it will create an interference pattern. As the slits get closed together the distance between light bands will increase, therefore, the right answer is option B.
