Light of composite wavelengths ( natural sunlight ) disperses into a visible spectrum passing through a prism, because of the wavelength dependent refractive index of the prism material ( dispersion ); that is, each component wave within the composite light is bent a different amount.

However, since the Earth reflects about 30 % of the incoming sunlight, the planet's effective temperature ( the temperature of a blackbody that would emit the same amount of radiation ) is about − 18 ° C, about 33 ° C below the actual surface temperature of about 14 ° C.

The lake, acting as a mirror, greatly increases the amount of sunlight that the grapevines of the region receive.

To calculate the amount of sunlight reaching the ground, both the elliptical orbit of the Earth and the attenuation by the Earth's atmosphere have to be taken into account.

For example, the magnitude of a river's current, i. e. the amount of water that flows through a cross-section of the river each second, or the amount of sunlight that lands on a patch of ground each second is also a kind of flux.

North-facing slopes receive about one-third the normal amount of sunlight, so plants growing there are similar to plants found at higher elevations, or in more northern latitudes.

The south-facing slopes receive the full amount of sunlight and are covered in vegetation typical of the Sonoran Desert.

The aerosol scale ( yellow to dark reddish-brown ) indicates the relative amount of particles that absorb sunlight.

Algal blooms limit the sunlight available to bottom-dwelling organisms and cause wide swings in the amount of dissolved oxygen in the water.

Part I: A Temperature-Humidity Index Based on Human Physiology and Clothing Science, R. G. Steadman, Journal of Applied Meteorology, July 1979, Vol 18 No7, pp861-873 Like the wind chill index, the heat index contains assumptions about the human body mass and height, clothing, amount of physical activity, thickness of blood, sunlight and ultraviolet radiation exposure, and the wind speed.

" Planting on hillsides, especially those facing north ( in the southern hemisphere ) or south ( in the northern hemisphere ), is most often in an attempt to maximize the amount of sunlight that falls on the vineyard.

He believed that early-morning sunlight passing through dew-drops on flower petals transferred the healing power of the flower onto the water, so he would collect the dew drops from the plants and preserve the dew with an equal amount of brandy to produce a mother tincture which would be further diluted before use.

or increase the amount of exposure to sunlight ( it has been estimated that 30 minutes of exposure to mid-day sun twice a week is adequate for most people ).

Examples include changing soil pH or fertility levels, irrigation practices, amount of sunlight, temperature, or the use of beneficial animals ( e. g. chickens ) or insects ( e. g. ladybugs ).

The amount of sunlight and daytime temperatures will also affect breeding timing.

With increasing depth underwater, sunlight is absorbed, and the amount of visible light diminishes.

The current solar income of the Earth, or an ecozone or ecoregion or any area, is the amount of solar energy that falls on it as sunlight.

He believed that early morning sunlight passing through dew-drops on flower petals transferred the healing power of the flower onto the water, so he would collect the dew drops from the plants and preserve the dew with an equal amount of brandy to produce a mother tincture which would be further diluted before use.

If such an impact occurred on land or the floor of a shallow sea, it could cause large amounts of dust or ash to be thrown into the Earth's atmosphere, blocking the Sun's light and dramatically lowering the amount of sunlight reaching the Earth's surface.

Independent research in Israel and the Netherlands in the late 1980s showed an apparent reduction in the amount of sunlight, despite widespread evidence that the climate was actually becoming hotter.

The building features exterior glass walls individually tailored to the amount of sunlight, and cantilevered multi-story blocks which provide shade and give the building a distinctive look resembling a stack of books.

A single-axis tracking system positions the mirrors to retrieve the optimal amount of sunlight.

The controlled variables would be the type of plant, the type of fertilizer, the amount of sunlight the plant gets, the size of the pots, etc.

The cone's taper means that a given amount of movement of the actuator makes the surfaces approach ( or recede ) much more slowly than in a disc clutch.

An RTOS makes the promise that no more than an agreed upon maximum amount of time will pass between executions of subroutines.

Weber noted that the importance of subjectivity in social sciences makes creation of fool-proof, universal laws much more difficult than in natural sciences and that the amount of objective knowledge that social sciences may achieve is precariously limited.

* Exact scoring: A player who makes the exact number of tricks bid scores 10 plus the amount bid.

* Exact scoring with penalty: A player who makes the exact number of tricks bid scores 10 plus the amount bid.

* Exact scoring with penalty where points are multiples of 5: A player who makes the exact number of tricks bid scores 10 plus the amount bid multiplied by 5.

* Exact scoring with set penalty: A player who makes the exact number of tricks bid scores 10 plus the amount bid.

* Exact scoring with progressive penalty: A player who makes the exact number of tricks bid scores 10 plus the amount bid.

With friction, the route taken does affect the amount of work done, and it makes little sense to define a potential associated with friction.

The amount of clay content added to the graphite depends on the intended pencil hardness ( lower proportions of clay makes the core softer ), and the amount of time spent on grinding the mixture determines the quality of the lead.

The structure's walls consist of three components: an outer layer ( tilted inwards and made of many layers of stones whose size diminishes with height: mostly, lower layers consist of rubble masonry, while upper layers tend to ashlar masonry ) shaped like a tower, an inner layer, made of smaller stones ( to form a bullet shaped dome called " Tholos ": ashlar masonry is used here more frequently ), an intermediate layer of very small pieces and dirt, which makes the whole construction very sturdy: it stands only by virtue of the weight of its stones, which may each amount to several tons.

Since it makes no reference to any quantities involved in work ( such as p and V ), the Helmholtz function is completely general: its decrease is the maximum amount of work which can be done by a system, and it can increase at most by the amount of work done on a system.

Cells are able to survive outside the body for a limited amount of time, which makes them ideal indicator organisms to test environmental samples for fecal contamination.

DSP often makes recorded speech sound less natural, although some systems use a small amount of signal processing at the point of concatenation to smooth the waveform.

There's still a tremendous amount of value to Apps Hungarian, in that it increases collocation in code, which makes the code easier to read, write, debug, and maintain, and, most importantly, it makes wrong code look wrong.

In Federalist No. 84, Hamilton makes the case that there is no need to amend the Constitution by adding a Bill of Rights, insisting that the various provisions in the proposed Constitution protecting liberty amount to a bill of rights.

The large amount of mud and sand discharged into the river makes the Yellow River the most sediment-laden river in the world.

The amount of methane potentially trapped in natural methane hydrate deposits may be significant ( 10 < sup > 15 </ sup > to 10 < sup > 17 </ sup > cubic metres ), which makes them of major interest as a potential energy resource.

Federal courts do not have parallel small claims procedures and apply the same civil rules to all civil cases, which makes federal court an expensive venue for a private party to pursue a claim for a small dollar amount.

This is a subject of much debate because large-scale pollution from other sources makes it difficult to measure the amount of pollution that comes specifically from fireworks.

It also makes the brake more sensitive to brake fade, as a decrease in brake friction also reduces the amount of brake assist.

Although the first continents formed during this eon, rock of this age makes up only 7 % of the world's current cratons ; even allowing for erosion and destruction of past formations, evidence suggests that continental crust equivalent to only 5-40 % of the present amount formed during the Archean.
