Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
light travels on its sources by energy transformations ;for example match=fire=heat=light=smoke or burnted candle wax
Sun is the primary source of heat here in the Earth. As time moves on, human developed new sources of heat and light. Some of it are the torches, lamps, candles and others
5 Sources of heat and light energy? 1. Sun 2. petroleum 3. natural gas 4. coal 5. solar energy
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
electricity, solid fuel, fire(using wood), infrared light, light bulb or heat lamp, gas e.t.c
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
A light bulb is one example.

There are natural and artificial light sources. A few examples of natural light sources include the Sun, stars, and candles. A few examples of artificial light sources include light bulbs, lamp posts, and televisions.
sun,star
no
Artificial light.
A primary light source is one that actually produces light, such as a light bulb or the sun. A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.
fire for heat,light and sun for light.
Those are usually called "lamps" or "light bulbs".
the sun.... its both.....
