Light is a form of energy that enables us to see objects in their various colors.
Light is a form of energy that can be classified as visible and invisible (relative to humans). Visible light is the color spectrum (see #3) and invisible light is X-rays and such.
The physical quantity that differentiates Visible light energy from invisible light energy is frequency.
Light is a form of energy that has a frequency and therefore is a wave, and it has an oscillating electric field and an oscillating magnetic field.
Light is a form of energy which propagates as waves and has a frequency that allows it to resonate with mediums.
Because of resonance, humans are able to see. Resonance is also the reason why some objects are transparent and some are translucent.
Light is a form of energy that is composed of packets, each packet has a quantized amount of energy which is proportional to the frequency. The quantum of light is called a photon.
Light is a form of energy that propagates at the speed of light, which is constant regardless of the speed of the source or the observer.
