Wave Particle Duality of Light
The wave theory of light coexists with the particle nature of light, as described by the quantum theory of light (photon theory).
According to quantum theory, light exhibits both wave-like and particle-like behavior, depending on the experimental conditions and the phenomena under consideration.
Particle-Like Behavior of Light
In certain experiments and observations, particles behave as localized entities with distinct positions and momenta.
When particles interact with detectors or undergo measurements, they exhibit discrete behaviors, such as localized impacts on screens or detectors in experiments like the photoelectric effect.
Wave-Like Behavior of Light
In other experiments and observations, particles display wave-like properties, such as interference and diffraction, characteristic of waves.
Interference patterns, similar to those observed with water waves or light waves, are seen when particles, such as electrons or photons, pass through multiple slits or obstacles.

Wave Theory of Light
Wave theory of light postulates that a light source emits light waves that spread in all directions. A light wave on striking a mirror gets reflected according to the angles but with each wave turned back to front, it produces a reversed image. In this article, we will explore wave theory of light along with the history of wave theory of light. Also, we will discuss Huygen’s wave theory of light and its construction. Let’s start our learning on the topic “Wave Theory of Light.”
