WebThis stood as one of the earliest, and most eloquent, wave theories of light. Not everyone embraced it. Isaac Newton was one of those people. In 1704, Newton proposed a different take -- one describing light as corpuscles, or … WebIn optics, the corpuscular theory of light states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess impetus.This was based on an alternate description of atomism of the time period.. Isaac Newton laid the foundations for this theory through his work in optics.

Physicist Albert Einstein’s famous theory of relativity suggests that it is not possible to travel faster than … WebLight is energy that normally moves in a straight line, but often something gets in the way. When light runs into something, three things can happen – the light can bounce off, it can go through, or it can be absorbed. Often all three things happen at the same time. Light bounces off mirrors.
Web9. A red ladybird looks red because its body reflects red light while absorbing green and blue light. Special cells in our eyes see this light and tell our brains to understand it as red. 10.

WebLight is made up of a lot of energy with different wavelengths, so different objects absorb light of different wave-lengths, and reflect the rest. For example, if we look at a red apple, the apple is reflecting the red light energy, and absorbing the rest, so we see the apple as red.
