Understanding the Nature of Light The nature of light has fascinated philosophers, as well as ordinary people, for thousands of years. The light seemed something ordinary and at the same time something very mysterious, magical. According to today’s criteria, a truly scienti c approach to the nature of light was initiated about 350 years
The particle-like nature of light is modeled with photons. A photon has no mass and no charge. A beam of light is modeled as a stream of photons, each carrying a well-defined energy that is dependent upon the wavelength of the light. The energy of a given photon can be calculated by: E = ℏ f . ℏ is called the Planck's
The nature of light. Light is everywhere. It extends from the large scale of the universe into our ordinary world. However, the physical understanding of the most common phenomenon, the light, has involved significant scientific ideas: classical mechanics, wave theories, quantum particles, relativity.
With the coming of the Scientific Revolution in the 16th and 17th centuries, optics, in the shape of telescopes and microscopes, provided the means to study the universe from the very distant to the very small. Newton introduced a scientific study also of the nature of light itself.

Hoffmann’s amusing and in-formative account—involving in part the wave-particle twins “tweedledum” and “tweedledee”—captured nicely the level of frustration felt in those days about the true .
OPTICS and the NATURE of LIGHT For most of human history, the facts of light and optical phenomena have been seen as central to the understanding of Nature. A historical review of ideas about light could certainly flll many books- no such attempt will be made here.
The document discusses the nature of light and key scientists who studied it throughout history. It describes Newton's particle theory of light, Huygens' wave theory of light, de Broglie's explanation of light's dual nature as both a particle and wave, and Maxwell's electromagnetic theory of light.
