Physics for Kids. Science of Light. What is light made of? This is not an easy question. Light has no mass and is not really considered matter. So does it even exist? Of course it does! We couldn't live without light. 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.
Light transmits spatial and temporal information. This property forms the basis of the fields of optics and optical communications and a myriad of related technologies, both mature and emerging. Technological applications based on the manipulations of light include lasers, holography, and fibre-optic telecommunications systems.. In most everyday circumstances, the properties of light can be ...

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm), or 4.00 × 10 −7 to 7.00 × 10 −7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths).
Over the centuries, our view of light has changed dramatically. The first real theories about light came from the ancient Greeks. Many of these theories sought to describe light as a ray-- a straight line moving from one point to another.Pythagoras, best known for the theorem of the right-angled triangle, proposed that vision resulted from light rays emerging from a person's eye and striking ....
Fans of science will love learning how light works and the many uses that we have for this incredible type of energy. The next time you turn a light fixture in your home on, you'll have a new found appreciation for how the light radiating from it works. The Science of Vision and Light.
Light is a form of energy that we can see. There are many sources of light, from blazing sunlight to the tiny glow of a firefly. We see objects when they give out light, or reflect it, into our eyes. Our eyes are able to process this light and turn it into an image in our brain.
Seymour Science here… today’s episode is all about where light comes from… with my expert friend, Albert! Pleasure to be here! Light is what helps us see things. It can come from different ...
We shared some cool color science experiments for kids, today we share some more science experiments for kids to learn about one of the senses via eyes: science experiments about light.These can be easily built into the Five Senses unit. There are many topics kids can learn about light. Today we share some ideas for kids to learn about prisms, light reflection, UV light, fluorescent light ...
Light is at once both obvious and mysterious. We are bathed in yellow warmth every day and stave off the darkness with incandescent and fluorescent bulbs. But what exactly is light? We catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water ...
