The nature of light
Keywords:
particle, wave, electromagnetic wave, photon, spectrumAbstract
This article starts with a brief introduction to the nature of light through a short review of the long battle of human beings to produce some light at night. We then examine the two basic answers given historically to the question about the nature of light. In the last section we recall the influence that the physics of the 20th Century (relativity and quantum mechanics) has had on our conception of light, to conclude with some comments about our perception of color.
