Explain Young's double-slit experiment and how it demonstrates the wave nature of light.

Young's double-slit experiment is a famous experiment that provides evidence for the wave nature of light. In this experiment, a coherent light source is directed towards a barrier with two small slits. The light passing through the slits creates two coherent sources of light that act as separate wavefronts. These waves then overlap and interfere with each other, resulting in an interference pattern of bright and dark fringes on a screen placed behind the slits.

The presence of these interference fringes demonstrates that light behaves as a wave, exhibiting constructive and destructive interference. This experiment supports the wave theory of light and confirms that light can exhibit interference patterns, similar to other wave phenomena.
