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.

For our purposes we will use light to mean all of the frequencies of radiation, known as the electromagnetic spectrum or EMS. Light is always in motion and cannot be stored, so it is a kinetic type of energy.

You might say that light is essentially "pure" energy, since it theoretically has no mass. Light is simultaneously a wave and a particle. The higher the frequency, the more energy the light or electromagnetic radiation contains. The greater the frequency, the more energy each particle, called the photon.

Light energy Definition

  • 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.

  • Light energy is made of electro-magnetic radiation and travels in a straight path



Example for Light energy

The moment you hear light what's that strikes is the sun light! Its that what makes you wake up early in morning giving you a sense of warmness and light. It heats the earth and makes the living beings to sustain. It balances the ecosystem and the world would have crashed without it!

Examples Light Energy

Yes sunlight is the best example for light energy. It is the natural source of light energy.

  • 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.

  • Light energy can also be converted into thermal energy when for example the sun heats up your black shirt or a brick wall outside.


  • Even a burning candle is an example for light energy.
