Wavelengths Sentence Examples

A microwave oven employs a device called a magnetron which produces strong magnetic fields with very short wavelengths (high frequency ).

Our perception of color arises from the presence of three types of retinal photoreceptors (cones) sensitive to different wavelengths of light.

All of the photosynthetic pigments are designed to absorb visible light across a range of wavelengths suitable for any number of environments.

We are planning to use infrared observations of type Ia supernovae to improve the accuracy of the results obtained at optical wavelengths.

Sunlight consists of electromagnetic radiation of wavelengths from 20 microns at the far infrared end to 200 nanometres at the far ultraviolet end.

Any surface that absorbs all wavelengths strongly will appear black.

Special modifications are required for use at infrared wavelengths.

The above image pair shows the core of NGC 1705 in both optical as well as near-infrared wavelengths taken with Hubble.

Small quantities may also be produced by certain ultraviolet light wavelengths.

This way we set up a direct link to the etheric wavelengths and the rest is easy.

However, the technology to do this at optical wavelengths is not yet available.

Astronomers detect light at sub-millimetre wavelengths in order to penetrate clouds of cosmic dust.

It will also be interesting to observe the HDF galaxies detected by ISO at submillimetre wavelengths, for example with SCUBA on the JCMT.

It is seen that as the coupling k becomes small these two wavelengths coalesce into one single wave length.

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.

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.

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.

Because of their long wavelengths, compared to the visible and infrared, microwaves have special properties that are important for remote sensing.

Normally, the human eye sees a broad spectrum of light with many different wavelengths, including infrared.

Numerous measurements have been made of the wavelengths of the brightest.

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.

A body which absorbs all radiations of all wavelengths would be called a "perfectly black body."

In another direction, making a small angle with the last, such that the projection of AB upon it amounts to a few wavelengths, it is easy to see that the mode of interference is the same as if there were no ruling.
