The difference between a long and short wavelength is the distance between two identical points on successive waves. Wavelength is also characteristic of the energy level of a particular wave, with shorter wavelengths being more energetic than longer ones.
Wavelengths are typically measured from the peak or trough of one wave to the same point on the next wave in the cycle. This is also a measure of frequency, which is the amount of wavelengths passing by a given point over the course of one second. Wavelengths have been classified according to their lengths, with audible waves and radio waves at the longer end of the spectrum and X-rays and gamma rays at the shorter end.
Differences in wavelengths can also be seen with the naked eye in the form of visible light. Shorter visible light waves correspond to specific colors, such as blue and purple, while red and orange have longer wavelengths. The white light that the human eye registers is simply a mix of all of the respective wavelengths of visible light. The wavelengths of light, just as those within the audible spectrum, go far beyond what is detectable by human senses, with infrared and ultraviolet wavelengths as two examples from opposite ends of the spectrum.Learn More
One of the most common uses of infrared rays is for wireless communication, such as with garage door openers, car-locking systems and handheld remote controls for televisions and other appliances. Since all objects emit some degree of infrared radiation, night-vision devices make use of their sensitivity to infrared rays to capture and transmit images when there is no visible light source. Heat-seeking missiles also rely upon infrared technology to track their targets in passive missile-guidance systems.Full Answer >
A spectroscope relies on separating light into its component parts because of the information that can be obtained from examining the wider spectrum of colors that composes white light as it is reflected off an object. Such information can include elemental composition as well as how much of a particular element makes up the object that is being looked at.Full Answer >
Installation costs, the need for special testing equipment and susceptibility to damage are notable disadvantages of using fiber optics. Although fiber optics offers superior throughput speeds for data transmission, its disadvantages often make it unfeasible to implement.Full Answer >
All electromagnetic waves move at the speed of light; subsequently, the wavelength and frequency of waves must be proportional, as the wavelength multiplied by the frequency equals the speed of light. As wavelength increases, frequency decreases, and as wavelength decreases, frequency increases proportionally.Full Answer >
