Light of a single wavelength falls on a screen with two narrow, closely spaced slits. On a second screen, a short distance beyond the first:
A)nothing will be seen since light cannot pass through narrow slits.
B)two bright lines corresponding to the two slits will be observed.
C)a totally random mixture of light and dark will be seen.
D)a series of bright lines with dark spaces in between will be seen.

This phenomenon is known as the double-slit interference pattern. When light passes through the two slits, it diffracts and creates an interference pattern on the second screen. This pattern consists of a series of bright fringes separated by dark spaces. This occurs because the light waves from the two slits interfere constructively and destructively, causing regions of maximum and minimum intensity on the screen.
