They reflect and refract the light, giving the depth and luminosity of a precious gem. |
|
When polarization is a concern, linear and birefringent polarizers can be used to remove, reflect, or refract one of the polarization components. |
|
Spectacles and contact lenses refract the light before it enters the eye, helping the eye to focus objects sharply. |
|
Metamaterial research is an emerging field that uses manmade substances to alter the way materials refract light or electromagnetic radiation. |
|
Visibility is affected by the plankton levels and thermoclines that refract the light so that an otherwise perfect image can get a woolly edge. |
|
The cornea and lens refract the incoming light rays to focus them on the retina at the back of the eye. |
|
They cut glass, they refract light into perfect hearts-and-arrows, and they have superlative fire and brilliance. |
|
Ideally we would like to refract the shadow ray too, but mathematically this is a much more difficult problem to solve. |
|
The different facets act both as surface decoration and refract light through the vessel. |
|
In a cylinder deviation, the cornea does not refract the light in the same way in all directions. |
|
The bevels refract light and provide a jeweled rainbow of light. |
|
The light will then glance off the diamond and refract across the glass-covered photograph of Mr. Maguire's long, serious face. |
|
He discovered how to refract lightwaves to create such beacons, not how to diffract them. |
|
This cunning cream is embedded with micro prisms that refract light away from wrinkles. |
|
The biggest advantage of this method is that results are obtained immediately with a portable refract meter. |
|
Skylights refract natural light through the store, and sensors determine when artificial light is needed. |
|
Here, the biblical tendency is clearly to refract the pagan borrowings so as to remove any allusion that may compromise the monotheistic aspect. |
|
Used to characterize the capacity of a transparent optical material to refract light and produce an optimal correction. |
|
It is caused by structural anomalies within the stone which refract or scatter incoming light. |
|
|
Delustering agents can control the lustre of the yarn by altering the way the individual fibres refract light. |
|
Clarity is the measure of how clearly a diamond is able to allow light to pass through it, reflect off of it, and refract within it. |
|
Their colour and clarity and the way they refract light make them desirable. |
|
The vitreous and aqueous humours both refract light and exert pressure to help maintain the shape of the eyeball. |
|
The opening female vocal ululations soon enough refract electronically, and the summoned whalesong dimension spires into an urgent metempsychotic groove. |
|
The cornea and the crystalline lens refract light that enters the eye. |
|
Second, a reduced amount of melamine is used in the manufacturing process to allow the inks to reflect and refract light for maximum visual impact. |
|
The formation of soluble alkalies at the surface can cause a flaking of thin layers there, resulting in layers that become detached and reflect and refract light differently from that of the glass body. |
|
Those words refract like sun from behind a cloud. |
|
Other metaphoric associations further refract her character through Metastasian, pre-Romantic, and even Flaubertian topoi. |
|
The light continues on through the crystalline lens which changes shape to refract the light reflected off the object in view: this is how the eye focuses. |
|
In its simplest form, a magnifying glass is a single convex lens which causes the light from the object being observed to refract and converge on the eye. |
|
Nanometre-sized pores no longer refract the light. |
|
Recently there has been a flurry of activity to diffract, refract and reflect light to disguise skin imperfections. |
|
These internal waves continue to flow eastward and to refract around coastal features. |
|
To see an example, click on the refract buttons. |
|
Both Alumina and Zirconia refract and transmit light in much the same way as a natural tooth, thereby giving the restoration a natural looking appearance. |
|
Ray tracing allows light to reflect from, and refract through, solids. |
|
This patented cream slips into wrinkles and fine lines and its millions of nanoprisms refract light so that both the wrinkle and the cream become invisible. |
|
Condensed water in the air may also refract sunlight to produce rainbows. |
