undulatory theory
Definition
Noun: - (Physics): A scientific theory stating that light is transmitted through space as a series of waves, as opposed to discrete particles. This theory is central to the understanding of wave optics and phenomena like interference and diffraction.
Usage
The term is used in historical and scientific contexts to describe the wave model of light propagation. - The undulatory theory was famously championed by Christiaan Huygens in opposition to Newton's corpuscular theory. - Understanding the undulatory theory is fundamental to explaining how light waves can interfere with each other.
Advanced Usage
- In historical debate: The term is often used when discussing the historical conflict between the wave theory and corpuscular theory of light.
- The eventual acceptance of the undulatory theory in the 19th century was a major milestone in physics.
Variants and Related Words
- Wave theory (of light): A more common modern synonym for "undulatory theory."
- Undulatory (adj): Having a wavelike motion or form.
- Corpuscular theory: The opposing historical theory that light consists of streams of particles.
Synonyms
- Wave theory
- Wave model of light
Related Phrases
- Huygens' principle: A key concept within the undulatory theory, stating that every point on a wavefront is a source of secondary wavelets.
- Huygens' principle is a cornerstone of the undulatory theory.
Noun
-
(physics) the theory that light is transmitted as waves
