Many chemical changes can be made with the help of light. With the help of sunlight, the tree produces food in its green leaves. So, light is a form of energy.
Following are some important Light energy transformation examples.
Light Energy Transformation Examples
Conversion of light energy to other energy:
Light energy to Chemical energy
When light falls on a photographic plate or film, a chemical reaction takes place and an image is formed. Plant food is produced by photosynthesis in the leaves of plants in sunlight. In these cases, light energy is converted into chemical energy.
Light energy to Electric energy
When light falls on a photo-electric cell, an electric current is generated. In this case, light energy is converted into electricity.
Light energy to Thermal energy
When the laser beam falls on a metal, the metal is instantly vaporized. In this case, light energy is converted into heat energy.
