Thomas Young was a British scientist who made significant contributions to the understanding of light and wave behavior. He is best known for his double-slit experiment, which demonstrated the wave nature of light.
In the context of waves, interference occurs when two or more waves combine and either reinforce or cancel each other out.
Huygens' principle: This principle states that every point on a wavefront acts as a source of secondary spherical waves, which then combine to form new wavefronts.
