Document Summary
The sun source of all energy on earth converts matter into energy energy (electromagnetic radiation) is emitted from the sun and we are able to capture the energy. Energy the capacity to do work. takes many forms: electromagnetic radiation (visible light, uv light), chemical energy (energy in chemical bonds that make up molecules, which make up matter), kinetic. One form of energy can be converted to another. Electromagnetic spectrum electro radiations emitted by sun measured in wavelengths wavelength inversely proportional to amount of energy shorter wavelengths = higher energy, higher wavelengths= lower energy length of wavelength determined by distance between the peaks. Absorption of light by chlorophyll ii colour is the result of wavelengths of light not absorbed by pigment. Photosynthesis sustains all life electromagnetic energy in sunlight captured by chlorophyll converts light energy into chemical energy sugar molecules contain some of this energy.
