The correct answer is: A. Isaac Newton.
Isaac Newton is credited for the Corpuscular theory of light. This theory states that light is made up of tiny particles called corpuscles. These corpuscles travel in straight lines and can be reflected and refracted. Newton’s theory was based on his experiments with light and his understanding of mechanics.
Christiaan Huygens proposed the wave theory of light. This theory states that light is a wave that travels through space. Huygens’ theory was based on his experiments with light and his understanding of waves.
Albert Einstein proposed the theory of relativity. This theory states that space and time are interwoven and that the speed of light is constant. Einstein’s theory was based on his experiments with light and his understanding of gravity.
James Clerk Maxwell proposed the electromagnetic theory of light. This theory states that light is an electromagnetic wave. Maxwell’s theory was based on his experiments with electricity and magnetism.
