Using the energy of light, plants combine a gas in the air called carbon dioxide with water in the soil. Through this process, called photosynthesis, plants make their own food. People and other animals then use plants for food. As plants make food, they also give off a gas called oxygen.
Light energy travels in waves or “rays” and can only be seen. In this educational video for kids, you will learn all about the properties light energy, both natural light and manmade or...
Welcome to our fun and educational video all about light energy! This engaging children's video will teach kids the basics of light in an entertaining and easy-to-understand way....
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. Light contains photons which are minute packets of energy.
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?
In the Light Energy module, students learn that light energy is the energy that allows them to see the matter around them. Through interactive lesson and activities, students explore the differences between natural and man-made light.
Light Energy. Light energy is sometimes called radiant energy. It is the only kind of radiant energy that is visible to the naked eye. Radiant energy is the energy that is carried by electromagnetic radiation. Some other examples of radiant energy are radio waves, microwaves, X-rays, and gamma rays. Electromagnetic radiation travels in waves.
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.

Light is a form of energy. When we say light, we mean the energy that we can detect with our eyes. When light enters our eyes, our brain interprets this into images we can ‘see’.
