Example Of Light Energy In The Body

E mc 2 equation in german born physicist albert einstein s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.

Example of light energy in the body.

Radio gamma rays x rays microwaves and ultraviolet light are some examples of electromagnetic energy. What is light energy. Any form of light has electromagnetic energy including parts of the spectrum we can t see. Photosynthesis is a concept in biology wherein food is synthesized in green leaves by the presence of light.

Light is thought to have energy packets called as photons. Light energy can also be converted into thermal energy when for example the sun heats up your black shirt or a brick wall outside. It is the energy collected from electromagnetic radiation. Electromagnetic radiation can be in many different forms all around us.

The energy of a photon is given by planck s constant i e. Noun an example of light ener. Kinetic energy can also be transferred from one body to another in a collision which can be elastic or inelastic. Electromagnetic energy or radiant energy is energy from light or electromagnetic waves.

Radiant energy is transmitted when the body cannot absorb it. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers bulbs and the sun. Light contains photons which are minute packets of energy. The energy from light is trapped as chemical energy and stored as food.

As you might have known this occurs by a process called photosynthesis. This is a form of kinetic energy because the moving particles carrying heat light and radiation from one source to another. Where e energy h planck s constant and f frequency of light. One example of an elastic collision would be one billiard ball striking another.

Light is the sole source of food generation for all living organisms on the earth. In physical theories prior to that of. In the equation the increased relativistic mass m of a body times the speed of light squared c 2 is equal to the kinetic energy e of that body. There are many example we see in our routine life carrying light energy like lightened candle flash light fire electric bulb kerosene lamp stars and other luminous bodies etc.

These are elementary particles of light and have wave nature and particle nature.
