📚 Understanding Huygens' Principle
Huygens' Principle, named after Christiaan Huygens, is a method for understanding wave propagation. It states that every point on a wavefront can be considered as a source of secondary spherical wavelets. The envelope of these secondary wavelets at a later time constitutes the new wavefront.
⚛️ Understanding Wave-Particle Duality
Wave-particle duality is a concept in quantum mechanics that states that every particle or quantum entity may be described as both a particle and a wave. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behavior of quantum-scale objects. Through experiments, scientists have demonstrated that light and matter can exhibit properties of both waves and particles, depending on the experiment.
