- Here is a simple definition of light energy for kids: Light energy is a type of electromagnetic radiation that we can see. It travels in waves and can move through empty space. It comes from sources like the Sun, light bulbs, and flashlights. Light energy helps us see things around us and gives off heat.

Dec 7, 2022 · Waves of Light. Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength.
Today scientists say light is a form of energy made of photons. Light is unique in that it behaves like both a particle and a wave. Why does light go through some things and not others? Depending on the type of matter it comes into contact with, light will behave differently.
Properties of Light. Light exists in two very different forms at the same time. One form is tiny particles called photons. The other form is waves. The easiest way to think about light is as waves. Light waves travel through space at a speed of about 186,282 miles per second (299,792 kilometers per second).
Electric lightbulbs and neon lights change electrical energy, which may be produced by chemical, mechanical, or atomic energy, into light energy. Light sources are necessary for vision. An object can be seen only if light travels from the object to an eye that can sense it.
Kids learn about photons in the science of physics, the particles of energy that make up light including properties and how they interact with matter.
