What is one characteristic of light exhibited under wave-particle duality?

Light exhibits wave-particle duality, which means it has properties of both waves and particles. One of the key characteristics of light as a wave is its ability to exhibit interference patterns. This phenomenon occurs when two or more light waves overlap and combine, creating regions of constructive interference (where the waves add together) and destructive interference (where the waves cancel each other out). The most classic demonstration of this is through the double-slit experiment, which showcases how light can produce a pattern of bright and dark fringes on a screen due to this interference.

Understanding this characteristic is crucial as it illustrates the wave nature of light, contradicting the idea that light behaves exclusively as a particle or that it only travels in straight lines without any wave-like interactions. The ability of light to interfere is essential in various applications, including optics, technology, and quantum mechanics.
