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.Know More
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.
Infrared light includes a range of wavelengths, spanning from one millimeter down to 750 nanometers. The top end of wavelengths include those used for communication, and the lower ranges are those used for visible light.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 >
As frequency increases, wavelength decreases. Frequency and wavelength are inversely proportional. This basically means that when the wavelength is increased, the frequency decreases and vice versa.Full Answer >
The infrared portion of the electromagnetic spectrum can be divided into three regions of infrared waves, all of which have different lengths. Far-infrared waves measure from 300 gigahertz to 30 terahertz, while mid-infrared waves range from 30 terahertz to 120 terahertz. Near-infrared waves range from 120 to 400 terahertz.Full Answer >
