intensity related to brightness of light
The frequency or wavelength that determines the color of light.
Polarization (angle of vibration) which is difficult to perceive with the human eye under normal conditions. Due to the wave-matter duality of matter, light exhibits the properties of both wave and matter at the same time. The exact nature of light is one of the major questions in physics.
