Final answer:
Diffraction is an example of a wave characteristic of light that is easily observed outside the laboratory. It occurs when light waves bend around obstacles or pass through narrow openings, creating patterns of bright and dark areas.
Step-by-step explanation:
Diffraction is an example of a wave characteristic of light that is easily observed outside the laboratory. Diffraction occurs when light waves bend around obstacles or pass through narrow openings, causing them to spread out and create patterns of bright and dark areas. This phenomenon can be observed in everyday life, such as when light passes through a small opening or when you see the colorful pattern created by sunlight passing through a prism.
