You guys were great, well Aimee was. And I greatly appreicate it for the help but I did another research and it was about duality of light... here's my paper. It's not as good as it should be but oh well. Im tired... done. If you all like to read it, here it is. Thanks again. Oh and if you like, feedback is welcome. Im sure there are plenty of errors..
Back in the 19th centery, the only thing people knew about lights was that
it was bright, it was fast, and it came in variety of colors. Very little was known
about it. Well light is a form of energy visible to the human eye. It is unknown
whether if it's waves or particles. Scientists such as Thomas Young, Albert
Einstein, Isaac Newton, Robert Hooke, and Christiaan Huygens all studied light
to see whether if it's made of waves or particles. Isaac Newton stated
in his theory he came up with, "Hypothesis of Light", that light was composed of
corpuscles which is particles of matter. He had one of many arguements against
the wave nature of light and that was waves were known to bend around the
obstacles while light had travelled only in straight lines. Light sometimes acts like
particles. Light also likes to act as a wave. But it can't be both because the
models of waves and particles are very different. The way they act
when traveling and passing through mediums is different. Whenever a light
acts as a particle, we call the particles that make up light a photon. Photons are
considered particles but they aren't regular particles of matter.
Protons do not have mass. Think of it more like as a bundle of energy.
In the early 1900's, Einstein mentioned that a ray of light travels in the path of the
photon. The traveling photons are in great number and travel in straight lines.
About the light being a wave, Young concluded that light must consist of waves.
The model of light as a wave is used to explain many of the basic properties
of light and it's behavior. Light waves as transverse waves don't need a medium
in order to travel. Also, light waves are called electromagnetic waves they
change to electric and magnetic fields. The light of the wave model explains
much of the observed behavior of light. An example, a light wave may diffract
through a narrow opening. People have asked if light is a wave or a particle,
the answer is it's neither of them. Though it may act like it, it's neither or.
Light acts as a wave, or as a particle, depending on what you do with
it and what you try to observe.
