Because of their long wavelengths, compared to the visible and infrared, microwaves have special properties that are important for remote sensing.
Our perception of color arises from the presence of three types of retinal photoreceptors (cones) sensitive to different wavelengths of light.

The various colors of visible light have wavelengths somewhat less than a thousandth of a millimeter, about the size of bacteria.
Spectral transmittance can be measured at either selected wavelengths or by using a scanning technique at regular intervals.
Below, you will see the spectrum of the Sun at ultraviolet wavelengths.
At visible wavelengths, however, dust has a greater effect on the light than the gas.
The infrared light enters the glasses, and the special filter lenses block other wavelengths of light and only allow infrared light to pass through.Advertisement
Everyone knows about the dangers of UV exposure -- those short wavelengths can damage skin and eyes -- but what about the longer wavelengths of infrared light?
The human eye can see only those wavelengths from red to violet; this portion of the electromagnetic spectrum is called "visible light."
It makes sense that infrared exposure would also increase at higher altitudes, as the long wavelengths do not have to pass through as much of the atmosphere at higher levels.
Serengeti's patented "Spectral Control System" selectively filters the various wavelengths of light, giving truer, clearer color perception.
But most non-scientists are not aware that there is a range of colors beyond visible light -- colors with both shorter and longer wavelengths.Advertisement
Longer than red wavelengths are infrared, microwave, and radio wave; shorter than blue are ultraviolet, x-ray, and gamma ray.
Lens types can be bonded together to create lenses that protect against multiple types of laser wavelengths.
These may be an option for those working with multiple wavelengths, but in some cases, you will need more than one pair of laser protection glasses.
It is important to have the eyewear made for the appropriate wavelengths involved when working with lasers.
Light breaks down pigment, but different colors absorb different wavelengths of light, and this determines how quickly the laser is effective on each color.
Rather, select a well-constructed welding lens since these will usually screen out about 100 percent of the ultraviolet and infrared wavelengths that could damage your eyesight if left unprotected.
Conceive a beam of plane polarized light to move among a number of particles, all small compared with any of the wavelengths.
This gives maximum u=about 8 cm./sec., which would not seriously change the form of the wave in a few wavelengths.
The degree of instability, as measured by q, is not to be determined from statical considerations only; otherwise there would be no limit to the increasing efficiency of the longer wavelengths.
The facility will be rapidly tuneable allowing data to be collected from small, weakly diffracting crystals over a wide range of wavelengths.
The wavelengths included are hydrogen alpha, hydrogen beta, doubly ionized oxygen and singly ionized nitrogen.
Domestic tungsten - Domestic tungsten lighting has a strong yellow/orange cast, because its color spectrum is shifted toward stronger wavelengths.
Normally, the human eye sees a broad spectrum of light with many different wavelengths, including infrared.

The enclosed area for each temperature represents the total emission of energy for that temperature, the abscissae are the wavelengths, and the ordinates the corresponding intensities of emission for that wave-length.
If a collective system be corrected for the axis point for a definite wave-length, then, on account of the greater dispersion in the negative components - the flint glasses; - over-correction will arise for the shorter wavelengths (this being the error of the negative components), and under-correction for the longer wave-lengths (the error of crown glass lenses preponderating in the red).
Spectroscopic Measurements and Standards of Wave-Length.- All spectroscopic measurement should be reduced to wavelengths or wave-frequencies, by a process of interpolation between lines the wave-lengths of which are known with sufficient accuracy.
