Esperiments that Newton did of light?

Answer 1

Even before Newton's famous experiments (1665) with light people were using prisms to experiment with colour, and thought that somehow the prism coloured the light. Newton obtained a prism, and set up his so that a spot of sunlight fell onto it. Usually, in such experiments a screen was put close to the other side of the prism and the spot of light came out as a mixture of colour. Newton realized that to get a proper spectrum you needed to move the screen a lot further away.

After moving the screen and achieving a beautiful spectrum he did his crucial experiment to prove that the prism was not colouring the light. He put a screen in the way of his spectrum, and this screen had a slit cut in it, and only let the green light go through.

Then he put a second prism in the way of the green light. If it was the prism that was colouring the light, the green should come out a different colour. The pure green light remained green, unaffected by the second prism.

Answer 2

This is the current paradigm as to understanding the nature of light and attempting to answer the age-old question: 'is light a wave or a particle?'. For a short history lesson, Issac Newton always thought light was a beam of tiny particles and the properties of light such as reflection could be explained as the perfect elastic collision of light particles on a hard (reflective) surface. His contemporary, Huygens, however, thought light was a wave but since Newton's name was better known, Newton's view was taken to be the norm for a over a century. However, in the early 19th century, Thomas Young showed via his famous double-slit experiment conclusively that light produced interference patterns that are only associated with waves and the wave theory became the new favourite for explaining the many wave-like properties of light, namely refraction, diffraction, and interference. However, that was not the end of the debate. In 1905, Einestein showed via the photoelectric effect that light was actually composed of particles that were called photons because the energy of light depended on its frequency, not amplitude as would be predicted by the wave model (this won Einestein a Nobel prize in 1921). With this discovery, scientists were faced with a paradox: is light actually a wave (as proven by the double-slit experiment) or a particle (as proven by the photoelectric effect)? The answer that they came up with was that light is something that has bothwave and particle-like properties and the true nature of light is both, but not either one or any combinations of the two (meaning light is not a 'wave of particles' or 'particles of waves'). This is just one of the mind-benders of quantum theory (other examples would be the famous Heisenberg uncertainty principle and the current understanding that all matter also exhibit wave-particle duality - meaning you exhibit wave-particle duality as well!).

Answer 3

Isaac newton conducted experiments with light using a prism to demonstrate that white light is comprised of a spectrum of colors. He showed that different colors of light can be refracted at different angles, leading to the discovery of the visible spectrum. This laid the foundation for our understanding of how light behaves and interacts with different materials.

Answer 4

he dug a big hole in the ground that put a triangle in the hole acing the sun then then put paper on the other side and saw a rainbow yey lol this is funny my brother just farted

Answer 5

Newton did a number of studies on light. He learned that light is made of a spectrum of colors and that a prism will separate the colors. He made the first reflecting telescope.
