Each color that makes up the spectrum of visible rays has a particular wavelength. The five principal colors—red, yellow, green, blue, and violet—make possible thousands of shades and hues, but are only a small slice of the electromagnetic spectrum. When light encounters a transparent material...
Light is a Wave Light is a form of energy known as electromagnetic radiation. The light we can see, the visible spectrum, are only a small portion of the energy that surrounds us every day. This is the visible spectrum. It is made of different colors. Can you think of a mnemonic to ...

Together, we refer to these forms of energy as the electromagnetic spectrum. You can think of it as a kind of super-big spectrum that stretches either side of the smaller spectrum we can actually see (the rainbow of light colors). There are lots of images of the electromagnetic spectrum ...
Stars emit light that falls within the visible spectrum. Scientists use an instrument called a Spectroscope to separate this starlight into its colors so that it can be studied. Spectroscopes break light into three different types. Continuous Spectrum Emission Spectrum Absorption Spectrum ...
The Electromagnetic Spectrum and Its Sources In 1665, when he was 23, Isaac Newton used a glass prism to disperse a beam of sunlight into a rainbow of colors (Figure 38. 24). He concluded that white light is a mixture of colors. The range of color, or spectrum as Newton called it, ...
电磁波谱(Electromagnetic spectrum) What are visible light, infrared ray, ultraviolet ray, X ray and gamma ray? Analysis: in the electromagnetic radiation of solar radiation, the electromagnetic wave that can cause the human eye vision is 0.76 ~ 0.4 microns (7600~4000) wave band, namely the li...
Ultraviolet (UV) radiation is a part of electromagnetic spectrum. It can be used to serve a variety of purposes. However, it could also be dangerous. UVB and UVC radiations aren't good for eyesight and can lead to skin cancer. The energy generated by this type of source is absorbed by...
Originally posted at the Mises Blog. Archived comments below. The issue of private property rights in the EM spectrum (airwaves) arises occasionally. To my knowledge there is not much systematic work on this topic; the David Kelley & Roger Donway’s 1985
image represents a specific color or wavelength region of the spectrum, from ultraviolet to near-infrared, and shows the wide wavelength range covered by Hubble. Astronomers chose to study NGC 1512 in these colors to emphasize important details in the ring of young star clusters surrounding the ...
