What is actually light
The word ' light ' is a simple word. But what a wealth of meaning behind hiding behind this concept. Because light is reflection, color, is a myth and is pure emotion. In addition, also light for safety. ' We all know what light is, but it's not easy to tell what it is... ' Rarely has anyone so right in my eyes as the English scholar Dr. Samuel Johnson (1709-1784).

Because what light is, we all know. But to be a description of? glow, While light still, nothing more and nothing less than reflection! Light is the beginning of everything. His reflection makes colors, objects and people visible to us. So not the light what falls but the light that makes everything visible by reflection of comes back. You can think of as the most beautiful glasses and most ingenious instruments light cannot reflect, you see nothing. What does light look like? How zietlicht, and I am talking now about natural light, look like? One look out is enough to answer. The sky, the roof of our world, is one gtoot and bright flat that is lit by the rays of the Sun. That roof reflects the light on Earth, through which we during the day above us in proportion to besides and among us a much higher light level. OS night, in the dark, it is exactly the other way around: the sky is dark, the Moon throws the light on the Earth that it reflects. That is why we have a greater clarity under and beside us, then as during the day above us. This is what we call the ' natural brightness ratio '. Otue gezichtszin is set to this natural brightness ratio. Our expectation of how light is the day uitzíet, opposite to that of the evening. Through the ages, before the invention of artificial lighting, we have also adapted to those natural brightness ratio. We got up when the Rooster started to crow and went with the chicken on stick. In the time in between we did what we needed to do. Where we lend a hand were helped by the sunlight that made possible that we could see that we were working. No wonder the Sun at that time had a divine status! Light is reflection What is light? Light is reflection and that's what it's all about when we talk about light. Light is nothing but reflection! We can see each other and our environment when light falls on it. Light itself is invisible and intangible. The only thing we can see is the source of light and the plane where the light can reflect. Reflection so, that's what it's about. The way that the light goes, is invisible. The daylight constantly changes of strength, while the color (the spectrum) as a chameleon always composition changes. So it is on a cold winter's day blue on a hot summer day roder of composition. The daylight can so at 5 for 3 or 5 about 3, before noon or after noon; or if it is snowing or miss, when the Sun is shining or when it rains a totally different impression of our environment and our perception.

Natural light changes color where you listed. What we can see, is the light source. We can only observe it myself if it is somewhere by is reflected. The way that light is invisible. Take but a flashlight late, in the dark, the light that comes out, fall on a tree. You see the tree and the light of the flashlight. What is in between, the light beam, remains invisible. While there are a lot of moisture in the air and the misses. Or if you have some non-blows in the light beam. Then it looks like you can see the light beam does. What you really perceive, is the reflection of light on the moisture or smoke particles in the air. Light makes so things visible by reflection. How does that reflect? It works like a ball you throw a ball horizontally. lesswith excellentheatreflecting against a wall, then he also at the same height in horizontal direction. You throw the ball a little slanted against the wall then bounced off the ball in the same corner, but in the opposite direction: the angle of incidence is the angle of loss. Reflects light in the same way as this ball. The light (that ball so) of a light source through a surface in your face, then do you experience glare. That happens for example in the case of glossy paper or plastic wallets, but also with frosted surfaces. The lighter the surface the higher the reflection. The amount of light that you experience depends on the reflection value of the materials and use of colour in the space in which it seems. A light-colored flat gives more reflection than, for example, a brown or black area. In a pitch black room, with Jet Black walls and ceiling and a concealed light source, you see nothing. Even if the light is on. Would you like to know more about light? Then order the book via the website * Light to life "of the author of this article.
