The end goal is to design a crude visible light spectrophotometer (vis-spec) or more correctly a colorimeter using the NXT brick, and two NXT light sensors. One sensor is used in the light active mode as a visible polychromatic light source (LED), and the other is used in the light inactive mode as a Figure 1
Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the
This means that there's a great deal happening around us that we're simply not aware of, unless we have instruments to detect it. Visible Light It s Visible!

This lesson offers activities that will help your students form a better understanding of what visible light is all about. Visible-light optical coherence tomography (vis-OCT) is an emerging imaging modality, providing new capabilities in both anatomical and functional imaging of biological tissue.

Visible light-based robust positioning under detector orientation uncertainty: A gabor convolutional network-based approach extracting stable texture features
Anything that glows or gives off light makes waves of what we call visible light. The sun, light bulbs, candles and fire are all things that people automatically think of when it comes to light, but visible light comes from many sources and in many colors. In the 17th century, Sir Isaac Newton explained this optical spectrum in his book Opticks. He was the first scientist to write about it but is not recognixed as the discoverer of visible light.
2017-05-01 · Visible light can be used as an ID system in different places such as buildings and subways. For example, if we are standing in room 12 in a certain building. A visible light ID system can be employed for identifying the room number and its building. Similarly a visible light ID system can be employed in subways, hospitals and airports .

Similarly a visible light ID system can be employed in subways, hospitals and airports . Since visible light from the sun hits the Earth’s surface at around 0.050 W/cm² in summer in Texas and 1 W is 1 J/second, this translates to around 30 minutes of sunlight. Visible light has different effects on different skin. How much visible light will affect your skin also depends on your skin colour. Visible Light Communication (VLC) can be used as a means of mobile connection (with a certain amount of disregard for security) and for communication in areas like hospitals where Wi-Fi and mobile phones are undesirable.

The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see.
Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. Visible light waves are the only wavelengths of the electromagnetic spectrum that humans can see.
