Colors are also associated with temperature, or the way that the colors are perceived. For example, red color waves are very long in length, while blue color waves are very short. Within that small area lie all of the colors that we can see, called the visible spectrum.Īll of the colors have different wave lengths that make them the colors that they appear. Light is just a minor fraction of the entire Electromagnetic Spectrum. The color that the apple does not absorb is reflected back to our eyes, causing us to see green. Why does the apple appear green? Light shines onto the apple, causing the apple to absorb every color in the spectrum besides the color green. To better explain how our eyes see color, imagine a green apple. Human beings by far have the best visual system structure - even better than a bird, who has to see small objects from high above! Every day, light waves reflect off of objects and into our eyes, which allows us to see the objects. In other words, light is power that we can see! Visible light is a small part of a large part of what is called the Electromagnetic Spectrum, which contains all of the energy types that travel through space in a wave-like manor. To put it simply, light is a type of radiant energy that we are able to visually perceive with our eyes. 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.

Fans of science will love learning how light works and the many uses that we have for this incredible type of energy. Light is truly a wonder to behold, but there is so much to understand about this amazing concept. The study of optics has allowed us to expand our knowledge on light waves and their interactions with all kinds of matter. Throughout the past century, there have been a number of scientific developments revolving around light. Light can be natural or manmade, but no matter how it is created, we utilize light every single day. It could be the glow from a light bulb in your bedroom or the warm shining rays that beat down from the sun. What is light? Light could be a number of different things, depending on the circumstances.
