Light energy is the only visible form of energy. Lots of things about light energy with corresponding pictures are discussed here. To get detailed information on light energy, dig this page. Click here to know more about light energy.
Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path. In everyday we use the word “light” for at least 10 times a day!! Have you ever think about the energy we get from the light. Light is all around us. It has the ability to tan or burn our skins, it can be harnessed to melt metals, or heat our food. Light energy posed a huge challenge for scientist up to the 1950′s.
Light energy refers to the electromagnetic energy that is visible to the human eye.
Light energy is energy that travels in straight lines called rays that fan outward from the source of the light. From the picture you can see how light energy travels in straight line.
Light energy is made of electro-magnetic radiation and travels in a straight path.
As shown in this picture, Light energy can be converted into chemical energy when the plants absorb the light energy; they convert it into chemical energy for their own nutrition.
Another real life example is the sun, the sun gives plants light energy which afterward is converted into chemical energy.
Even a burning candle shown in the picture is an example for light energy.
Some of the important and interesting sources of light energy are listed below,
Incandescence, source of light
Phosphorescence, source of light
Electric Discharge, source of light
Fluorescence, source of light
Chemiluminescence, source of light
Bioluminescence, source of light
At high temperatures, luminous light sources begin to emit light.
The process of emitting light because of a high temperature is called incandescence.
incandescent light is shown in the below picture.
Some materials, called phosphors store the energy and then release it gradually as light energy.
The process of emitting light for some time after receiving energy from another source is called phosphorescence.
Phosphorescence light source can be seen in the picture shown here.
