At different altitudes, various colours are created by interaction of electrons in the solar wind with atmospheric gasses as seen in Figure 9. © William Copeland Where on Earth can you see the lights? As the
Animals see differently – from simple eyes that only tell the difference between light and dark, to complex eyes that can see colours and depth perception.
Isaac Newton was perhaps the first person to observe that colour is not inherent to all objects; rather, an object either reflects or absorbs coloured light, and what is reflected is what our brains will process as a specific colour. The colour spectrum is made up of three primary colo...
A very small segment of the EM spectrum, termed the visible spectrum, roughly 390 (violet) – 710 (red) nanometers (nm), is what humans are able to perceive. Other organisms can see other EM waves. Ourcats, dogs, and hedgehogs can see UV light, and insects use their UV vision to ...
Colour can be described in terms of hue (dominant wavelength of the visible spectrum), saturation (the amount of white light mixed in with a hue) and brightness (intensity of light). Any desired hue of light can be produced when various amounts of the three primary colours of light (red...
A colour space is a graphical representation of how all the different colours are reproduced, and in 1931 the International Commission on Illumination (CIE) published its ground-breaking research into the relationship between the visible spectrum and how it’s perceived by human colour vision. Each...
Our eyes have capability to see colors that may different between people/species but that doesn’t mean the color isn’t real. We just see in what we refer to as the visible spectrum. We have technology that allows us to see in a much broader range of the spectrum.. ...
For instance, each pixel of an image file is made up of three bytes of data that correspond to the colours red, green, and blue; some image formats allocate an additional fourth byte to transparency or alpha. What LSB Steganography does is change the last bit of each of those bytes to ...
What is the importance of the hollow solar panel component of the solar street light system shown below? What is meant by the polarization of light? What is the evidence that white light is a composite of seven colours? What is meant by scattering of light?
colour you could imagine (mainly white led streetlights, plus yellow/orange and magenta leds in greenhouses) + still HPS. Flower growers experiment with different "light spectrum recipes", but the details of the spectrum are kept secret. The colours and intensity may change...
