What are the 4 main properties of light?

The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature.

What exactly is light?

Light, or Visible Light, commonly refers to electromagnetic radiation that can be detected by the human eye. … Light can also be described in terms of a stream of photons, massless packets of energy, each travelling with wavelike properties at the speed of light.
