Electromagnetic waves
Electromagnetic waves in fact there is always around us, one example is the sun's rays, these waves do not require an intermediary in perambatannya medium. Another example is radio waves. But the spectrum of electromagnetic waves are composed of various other types of waves, which are distinguished by frequency or wavelength.For that here we will learn about the range of the spectrum of electromagnetic waves, special characteristics of each of the electromagnetic waves in the spectrum and examples and application of each of the electromagnetic waves in everyday life.
Electromagnetic waves are waves that can propagate even if there is no medium.Electromagnetic energy travels in waves with some characters that can be measured, namely: wavelength / wavelength, frequency, amplitude / amplitude, velocity.Amplitude is the height of the wave, while the wavelength is the distance between two peaks. Frequency is the number of waves passing through a point in one unit of time.The frequency depends on the speed of the wave climbed. Because the speed of electromagnetic energy is a constant (speed of light), wavelength and frequency is inversely proportional. The longer a wave, the lower the frequency, and the shorter the wave the higher frequencies.
Electromagnetic energy emitted, or released, by all the time in the universe on a level that berbedabeda. Higher levels of energy in an energy source, the lower the wavelength of the energy produced, and the higher frequencies. Different characteristics of the wave energy is used to classify the electromagnetic energy.
The characteristics of electromagnetic waves:
From the description above we can conclude several characteristics of electromagnetic waves is as follows:
1. Changes in electric and magnetic fields occur at the same time, so that the two fields have a maximum and minimum prices at the same time and at the same place.
2. Direction of electric field and magnetic fields perpendicular to each other and both perpendicular to the direction of propagation.
3. Of characteristic No. 2 obtained that electromagnetic waves are transverse waves.
4. Like the waves in general, an incident electromagnetic wave reflection, refraction, interference, and diffraction. Also experienced events including the polarization due to transverse waves.
5. Rapid propagation of electromagnetic waves depends only on the properties of electric and magnetic medium which he passes.
Visible light by the eye is not simply the type that allows electromagnetic radiation.The opinion of James Clerk Maxwell showed that electromagnetic waves other, in contrast to visible light by the eye in she had a wavelength and frequency, there may be. These theoretical conclusions were remarkably reinforced by the Heinrich Hertz, which is able to produce and meet the two waves are visible to the eye that was predicted by Maxwell. A few years later Guglielmo Marconi demonstrated that the waves are invisible eye that can be used for communication without wires, so what's his name menjelmalah radio. Now, we use also for television, X-rays, gamma rays, infrared rays, ultraviolet rays are examples of electromagnetic radiation. Everything can be learned through the ideas of Maxwell.
