What is the percentage of solar radiation reflected from a surface?
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
What happens when the sun's rays hit the Earth's surface?
Radiant energy will either be reflected or absorbed by a surface. The usual rule regarding this reflection depends on the color of the object and the color of the light. For example, a red object only reflects red light, and absorbs the rest. A blue object only reflects blue light, and absorbs the rest. This goes for all of the colors. When radiant energy is absorbed, the object will heat up. Hope this helps!
When you see a coloured object what are you really seeing?
That part of the visible spectrum that is reflected from its surface.
Why are image reflected from a rough surface not as clear as those reflected from a smooth surface?
Some light that falls on any surface is scattered back (reflected). A rough surface tends to scatter the light in different directions while a smooth surface tends to scatter more of the original (incident) rays straight back. This explains why a smooth surface reflects a "clearer" image than that reflected from a rough surface.
What is the name of the amount of sunlight that the surface of the moon reflects?
In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".

The reflective quality of a surface is known as its?
Albedo is the fraction of solar energy (shortwave radiation) reflected from the Earth back into space. The albedo of an object is a measure of how strongly it reflects light from light sources such as the sun. It is therefore a more specific form of the term reflectivity.
What can happen when radiation strikes an object?
It can reflect, absorb or scatter off the object.
How much solar energy is absorbed and how much is reflected from the earth's surface?
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
How much solar energy is reflected back into space?
About 30% of incoming solar radiation is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%(Source: NASA. see link below)A:Scientists use the term albedo to describe the percentage of solar radiation reflected back into space by an object or surface. A perfectly black surface has an albedo of 0 (all radiation is absorbed).A perfectly mirror-finished surface has an albedo of 1.0 (all radiation is reflected).Earth's average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space (from land, sea, clouds, ice and atmosphere) and 70 percent is absorbed.From point to point on the Earth's surface, the albedo varies; high for clouds or snow, low for cities and paved areas, intermediate for vegetation. Overall, averaging the bright areas with the cities, the Earth's albedo is about 0.3 or perhaps just a little higher; 0.34 or so.Well, all of it is not. Some of it is absorbed by the oceans, some by dry land, and some by the ice caps.
Which type of body heat loss is characterized by heat transfer from the surface of one object to the surface of another object without actual contact?
Radiation.

When you see a coloured object what are you really seeing?
That part of the visible spectrum that is reflected from its surface.
Why the object appear when you put the object in front of mirror?
light bounces off an object and on to the miorror surface where it is then reflected at the same wavelength as it was casted on to there with
Why does a specific color reflected by an object give color to it?
White light contains all the colors mixed together. A colored object has a pigment on its surface that ABSORBS all these colors except one. This one color is reflected back off the object. Thus, as we see the object by this reflected light coming from the object into our eyes, the object appears to be colored.
What fraction of earth gravity the moons gravity?
An object on the Moon's surface weighs 16.55% as much as the same object weighs when it's on the Earth's surface. The fraction is roughly 1/6.
