light energy?

Answer 1

Light energy is also caled Radiant energy .

Radiant energy is the energy of electromagnetic waves.The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and, like all forms of energy, its SI unit is the joule.

Radiant energy is generally thought of as radiation emitted by a source into the surrounding environment. It propagates in the form of electromagnetic waves, or traveling subatomic, atomic or molecular particles.


Specific forms of radiant energy include electron space discharge, visible light, vacuum energy, and other wave types.

Radiant energy is exhibited in the spontaneous nuclear disintegration with emission of particulate or electromagnetic radiations.

Answer 2

light energy?
what about it?
Do you remember the electromagnetic spectrum?
The electromagnetic spectrum is a continuously self progagating wave of electric and magnetic fields. These waves are a characteristic of energy. The spectrum varies in wavelength and frequency (which means energy and intensity). Starting from the smallest wavelength are gamma rays, it increases through to xrays, ultraviolet, visible light, infrared, microwaves then radiowaves.
So yes, visible light (e.g. the stuff that comes out of our light globe (white light is a mixture of all visible lights (red orange yellow green blue indigo and violet) is energy.
what else do you need to know?
ummmm...
the electromagnetic spectrum is made up of particles called photons. A photon can give its energy to matter (either fully, partially or not at all). Which brings me to two last points :
1. energy can turn into into another form. e.g. light energy can become heat energy. light energy can become electrical energy.
2. energy can't be created or destroyed. it's just turned into something else.

i hope that helped

Answer 3

what about light energy?

well, if you want its definition... here it is:

it is the energy that produces sensation of brightness that makes seeing possible

Answer 4

energy from sunlight or solar energy
