What is another word for corpuscular theory?
Pronunciation: [kɔːpˈʌskjʊlə θˈi͡əɹi] (IPA) 
Corpuscular theory, also called the particle theory of light, is a scientific concept that explains light as being made up of tiny particles called "corpuscles". There are several synonyms that can be used to describe this theory, including the particle theory of light, the corpuscular hypothesis, corpuscular radiation theory, and the corpuscle theory of light. These terms are often used interchangeably and refer to the same concept. The corpuscular theory was first proposed by Sir Isaac Newton in the 17th century and remained a prominent theory until the 19th century when it was superseded by wave theory. Nevertheless, it played an essential role in our understanding of light and paved the way for the development of quantum mechanics.
