1.electric light ,because without electricity ,an electric light would not be a light source...............................2. a candle ,because without the flame from the match's flames the candle would not be alight source.......................................................the moon ,because it reflects the light that is giving to it by the sun un, so if there wasn't a sun the moon wouldn't be a light source
Anything that is man made, like a light bulb, laser, floodlight etc.
Man made sources of light are things such as fire, light bulbs and flashlights. Light bulbs and flash lights are powered by electricity.
Electric lights, gas lights, and lasers are examples.
lasers are one example
Two words... Light Bulbs.
torch, lighted candle, iron, oven toaster
Two examples are a candle and a torch.
electricity, solid fuel, fire(using wood), infrared light, light bulb or heat lamp, gas e.t.c
No. A light bulb is.
Light is light. Once it's created it is what it is Or perhaps your mind is so closed as to believe that sun light is the only real form of light. In that case you should change your question
No.Ligtning is not a heat source.Unless u think that the electric of the lightning have heat.<<Previous answer:Yes.Fire is a heat source and a light source. If you were meaning light bulbs, then yes again. The electric current flowing through the filament (excuse spellings) causes the wire to glow (creating the light) and generate heat. This is caused by the resistance in the wire. Even tiny little leds generate heat and light. I may be wrong here.... but I dont think any light source does not generate heat of some kind. Heat is light radiation in the near and far infra-red range. You can have light sources that generate very very very little infra-red light, for example flourenscent lights produce light in the visible range almost exculsively BUT yes all light sources do produce some heat as an unavoidable energy loss.>> Lightning is a heat source. It is electricity rapidly flowing through a column of ionized air. Thunder is the shock wave it generates in the atmosphere. Think of the crackling noise a static filled blanket makes. Move it in the dark and you can see the static letting go - like lightning in miniature.
Artificial light.
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.
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
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.....
