Visible light is part of the electromagnetic spectrum. The Sun is our main sources of light. The other sources for visible light are the moon and the stars. It is essential to realize that we cannot see ultraviolet or infrared wavelengths. However, we are able to detect the red and blue ...
The Electromagnetic Spectrum The electromagnetic spectrum is the known span of energy that exists in the world as we know it. It includes all energy measurements on both sides of the visible spectrum. These same colors appear in every rainbow and refracted white light. Occasionally you’ll see a...

What made the link from then to now was the development of wireless communication. Marconi was the first to develop and perfect this system, using the recently-discovered “air waves” that make up the electromagnetic spectrum.[B]Between 1896, when he applied for his first patent in England ...
it is helpful to grasp a few basics about the electromagnetic spectrum. Electromagnetic frequencies (EMFs) are expressed in terms of units called hertz (cycles per second), abbreviated as Hz, where the higher the frequency, the smaller the wavelength. The spectrum begins with direct current and ...
The Electromagnetic Spectrum Figure RP 4: The electromagnetic spectrum. Electromagnetic waves span a wide range of frequencies (and, accordingly, wavelengths). This range of frequencies or wavelengths is called the electromagnetic spectrum. The part of the spectrum most familiar to humans is probably ...
Electromagnetic Spectrum - Radio Waves On The Right The shorter the EM wavelength (higher frequency), the more energy it has. Higher energy wavelengths beginning somewhere in the ultra-violet out to Gamma wavelengths are classified as ionizing radiation. You know, radioactive. ...

Electromagnetic radiation is measured in wavelength “λ” or in frequency “f”. Both quantities are related by the equation λ = c ÷ f, where "c" is the speed of light (3 x 10-8m/s). Infrared radiation wavelengths fall outside the visible range in the electromagnetic spectrum; see ...
The electromagnetic spectrum is a continuum with low-frequency long waves at one end and high-frequency short waves at the other. Visible light, the most familiar electromagnetic waves to most of us, occupies a slice of the spectrum with frequencies of around 1015 Hz (waves per second). The...
