The light we see can be divided into two categories: Light sources and reflected light. The sources of light can then be looked at in two sub categories: Natural light sources and artificial light sources. Both of these types of light sources can either come from hot sources or from cool sources. The organizer below will help you to follow this ...
In luminous objects, the input energy transforms into light energy. Common forms of input energy are chemical energy, electrical energy, nuclear energy, and thermal energy. When designing a light source, engineers consider not only the brightness, location, attractiveness, and cost of the light source.
Energy can be moving in the form of light, heat, sound and moving objects. Energy can be stored in food, wood, coal, oil and natural gas. In the table, fill in examples of different sources of energy.
The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.
