What is light energy simple?
What is light energy? Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun.
Why light is an energy?
In fact visible ‘light’ is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like ‘wave-packets’, called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).

What type of energy is a flashlight?
In a flashlight, chemical energy in the batteries is converted to electrical energy when the circuit including the batteries, switch and light bulb is completed. The electrical energy is converted to light (electromagnetic / radiant energy) and some heat (thermal energy) by the light bulb.
What type of energy is light bulb?
In the light bulb, the flow of charge through the filament heats it up and causes it to glow. In this way, the light bulb converts electrical energy to heat energy and light energy.
What type of energy is a radio?
The type of energy utilized by a radio is known as electromagnetic radiation. Electromagnetic radiation includes radio waves, X-rays, microwaves, and visible light. Simply put, electromagnetic radiation involves the flow of photons through space, and photons are the basic unit of all forms of light.
