corpuscular theory of light
Definition
- Noun:
- A historical scientific theory in physics: The corpuscular theory of light is the theory that light consists of a stream of discrete, tiny particles, or corpuscles. This theory was notably proposed by Sir Isaac Newton as an alternative to the wave theory of light.
Usage
- The term is used in historical and scientific contexts to discuss the development of theories about the nature of light.
- It is often contrasted with the wave theory of light.
Examples
- Noun:
- Newton's corpuscular theory of light was influential for over a century.
- The debate between the corpuscular theory of light and the wave theory was a major topic in classical physics.
Advanced Usage
- "to support/advocate the corpuscular theory of light": To argue in favor of this particle-based model.
- Several 18th-century physicists continued to support the corpuscular theory of light.
- "the demise/decline of the corpuscular theory of light": Refers to the theory being superseded by evidence supporting wave-like behavior.
- The results of diffraction experiments led to the decline of the corpuscular theory of light.
Variants and Related Words
- Corpuscular theory (n): A shortened form often used in the same context.
- The corpuscular theory was eventually challenged by new evidence.
- Corpuscle (n): A minute particle; a term for the hypothetical particles of light in this theory.
- In this model, each corpuscle was thought to travel in a straight line.
Synonyms
- Emission theory: Another name for Newton's particle theory of light.
- Particle theory of light (historical context): A descriptive synonym.
Related Phrases
- "Corpuscular versus wave theory": A phrase describing the historical debate.
- The 19th century resolved the corpuscular versus wave theory debate in favor of waves, until the advent of quantum mechanics.
Noun
-
(physics) the theory that light is transmitted as a stream of particles
