An introduction to the types of waves in the electromagnetic spectrum

In addition, radiation from various parts of the spectrum has been found to have many other uses in communications and manufacturing. Terahertz radiation Main article: Terahertz radiation Terahertz radiation is a region of the spectrum between far infrared and microwaves.

How can we "see" other parts of the spectrum?

This one is the historic 66cm 26inch refractor telescope at the U. Electromagnetic Spectrum: Rules of Thumb Three rules that apply to electromagnetic waves in general are as follows:. X-rays were discovered by German scientist Wilhelm Roentgen. When you close your eyes, the world doesn't cease to exist just because there's no light to see by.

An introduction to the types of waves in the electromagnetic spectrum

In artificial generation of radio waves, an electronic device called a transmitter generates an AC electric current which is applied to an antenna. Fireflies, light bulbs, and stars all emit visible light. White light is a combination of lights of different wavelengths in the visible spectrum. How are they created, and how do they travel? Astronomers can observe some infrared wavelengths by putting telescopes on mountain tops. Click the small image on the right to see quite a nice diagram of the spectrum from NASA. X-ray photons have energies in the range eV to , eV or keV. Wavelength is measured in meters. Show me a chart of the wavelength, frequency, and energy regimes of the spectrum Why do we put telescopes in orbit? Interference An important property of waves is the ability to combine with other waves. In reception of radio waves, the oscillating electric and magnetic fields of a radio wave couple to the electrons in an antenna, pushing them back and forth, creating oscillating currents which are applied to a radio receiver.
