What Does Light Energy Mean
Light energy is defined as how nature moves energy at an extremely rapid rate and it makes up about 99 of the body s atoms and cells and signal all body parts to carry out their respective tasks.
What does light energy mean. Light is a form of energy which our sense of sight can detect. Light has a dual nature that is revealed only in quantum mechanics. Light is nature s way of transferring energy through space. The light hits your retina and sets off a particular pattern of chemical changes in your cone cells which your brain recognises as green.
However neither a classical wave model nor a classical particle model correctly describes light. The sun is the closest star to the planet earth and radiates light energy. Chemical energy chemical energy is released or absorbed by chemical reactions. Also called lu mi nous en er gy radiant energy.
Electrical energy this is energy from the movement of charged particles such as protons electrons or ions. Magnetic energy this form of energy results from a magnetic field. It is made of electro magnetic radiation and travels in a straight path. Electromagnetic radiation to which the organs of sight react ranging in wavelength from about 400 to 700 nanometers and propagated at a speed of 186 282 miles per second 299 972 kilometers per second considered variously as a wave a stream of particles or a quantum phenomenon.
The speed of light is about 300 000 km s. Photons are the particles that light is made up of which are like tiny packets of energy. In its simplest form quantum theory describes light as consisting of discrete packets of energy called photons. It is produced by breaking or forming chemical bonds between atoms and molecules.
What is the speed of light. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers bulbs and the sun. Since light itself is energy then another definition is relevant. Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes.
Light energy is a form of electromagnetic radiation that can be seen by the human eye. Light photons are a form of energy.
