To Newton's atomic theory of light, there was the very successful wave theory, which explained typical light behavior such as refraction (the change in the direction of propagation of light when ...

This represented a challenge to "wave theory", which had been advocated by 17th century Dutch astronomer Christiaan Huygens. . These theories were first communicated in 1678 to the Paris Academy ...

I. THE emission theory of light prevailed for a century after Newton's death. During this time his “Opticks” was regarded as of equal importance as his “Principia,” and his emission theory ...

Isaac Newton considered that light propagates as particles in his theory of light, which prevailed until it was replaced by the wave theory of light in the 19th century to explain diffraction ...

This is called wave-particle duality. The theory dates back to the 17th century when Isaac Newton suggested that light is composed of particles.
