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).
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 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!
How do you get heat from the sun?
The sun's heat is radiated to the earth which enters the atmosphere. This heat warms up the surface but is then reflected back into space. But, as the atmosphere's amount of greenhouse gases is increasing, less heat is escaping from the earth's surface and is getting trapped. This results in what we call 'global warming' as the earth's temperature heats up.
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).
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 happens when light hits the surface of an object an angle?
When light hits the surface of an object at an angle, it can be reflected (bounced off), refracted (bent), or absorbed by the object. The amount of light that is reflected or refracted depends on the surface properties of the object, such as smoothness and transparency.
What is the light called when it has bounced off another object?
The light that has bounced off another object is typically referred to as reflected light. This occurs when light waves strike the surface of an object and are redirected or "reflected" off the surface.
What happens to colors that are not absorbed by the object?
Colors that are not absorbed by an object are typically reflected off the surface of the object. These reflected colors are what we see and perceive with our eyes, giving the object its visible color.
What is it called when radiation bounces off an object's surface?
That process is called reflection. Radiation can bounce off the surface of an object, changing direction but maintaining its energy.
What two things happen to light when it strikes to an object?
When light strikes an object, it can be absorbed by the object, converting into other forms of energy, or it can be reflected off the object's surface, allowing us to see the object if the reflected light reaches our eyes.
When light hits an object it can be?
reflected, transmitted, or absorbed depending on the properties of the object's surface and material.
Can light energy be reflected by an object into your eyes?
Yes, light energy can be reflected by an object into your eyes. When light strikes an object, it can bounce off the surface in different directions. Some of this reflected light may enter your eyes, allowing you to see the object.
What two factors influence the color of an object?
The color of an object is influenced by two main factors: the wavelength of light that is reflected or absorbed by the object, and the composition of the object's surface that determines which wavelengths are absorbed and which are reflected.
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 is the type of body heat loss characterized by heat transfer from the surface of one object to the surface of another object without actual contact. This occurs through electromagnetic waves emitted by the warmer object and absorbed by the cooler object.
What controls the brightness of the color of an object?
The brightness of the color of an object is determined by the amount of light that is reflected by the object's surface. The color itself is determined by the wavelengths of light that are reflected, with the object appearing brighter or darker depending on how much light is reflected back to our eyes.
