The three most important characteristics of light are brightness, colour, and temperature. Brightness does not need much explanation, but colour and temperature are slightly more subtle concepts. Light is electromagnetic radiation visible to the human eye.
Herein, what are the four characteristics of light?
The direction of light can make or break a shot. Understanding these four characteristics of light — quantity, quality, color temperature, and direction — won't magically make you a better photographer. The information is important, sure.
What are the properties of a light wave?
There are three measurable properties of wave motion: amplitude, wavelength, and frequency. A definitive experiment was Young's double slit experiment, which demonstrated that light shined at two slits in a screen show an interference pattern characteristic of waves of light, rather than particles.
What is it light?
Light is part of the electromagnetic spectrum, which ranges from radio waves to gamma rays. Electromagnetic radiation waves, as their names suggest are fluctuations of electric and magnetic fields, which can transport energy from one location to another.
