Optical phenomenon

Optical phenomena are any observable events that result from the interaction of light and matter.

All optical phenomena coincide with quantum phenomena.[1] Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates. One common example is the rainbow, when light from the Sun is reflected and refracted by water droplets. Some phenomena, such as the green ray, are so rare they are sometimes thought to be mythical.[2] Others, such as Fata Morganas, are commonplace in favored locations.

Other phenomena are simply interesting aspects of optics, or optical effects. For instance, the colors generated by a prism are often shown in classrooms.

Scope edit

Optical phenomena include those arising from the optical properties of the atmosphere; the rest of nature (other phenomena); of objects, whether natural or human-made (optical effects); and of our eyes (Entoptic phenomena). Also listed here are unexplained phenomena that could have an optical explanation and "optical illusions" for which optical explanations have been excluded.

There are many phenomena that result from either the particle or the wave nature of light. Some are quite subtle and observable only by precise measurement using scientific instruments. One famous observation is of the bending of light from a star by the Sun observed during a solar eclipse. This demonstrates that space is curved, as the theory of relativity predicts.

Non-atmospheric optical phenomena edit

 
Green flash appears above the solar disc for a second or so. One such occurrence was taken from Cerro Paranal.

Other optical effects edit

Entoptic phenomena edit

Optical illusions edit

  • The unusually large size of the Moon as it rises and sets, the Moon illusion
  • The shape of the sky, the sky bowl

Unexplained phenomena edit

Some phenomena are yet to be conclusively explained and may possibly be some form of optical phenomena. Some[weasel words] consider many of these "mysteries" to simply be local tourist attractions that are not worthy of thorough investigation.[4]
