Final answer:
An example of destructive interference is when light passing through two slits creates gaps on a surface.
Step-by-step explanation:
An example of destructive interference is when light shining on a surface has gaps after passing through two slits. This phenomenon is known as the double-slit experiment, where a single beam of light passes through two narrow slits and creates an interference pattern on a screen. In certain areas, the waves from the two slits cancel each other out, resulting in dark spots or gaps in the light intensity.
