There is no special name. The fraction of sunlight which is reflected will be different from the fraction of other light. The reflectivity of a surface varies with the wavelength of the incident light.
There is no particular term. This is because the reflectivity of a surface varies across the electromagnetic spectrum so a surface which reflects a large proportion of blue wavelengths in sunlight may or may not reflect a similar proportion of red wavelengths.
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
Nothing. The cylinder's surface area does not have a GCF.
This is two problems. Surface area is measured in square units. The formulas for the area of different figures vary with the figures. The area of a regular four-sided figure is the length times the width. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, tenths of square units. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
A fraction of light refers to the portion of light that is transmitted, reflected, or absorbed when it encounters a surface or medium. This can be quantified mathematically as the ratio of the intensity of the transmitted or reflected light to the intensity of the incident light. Fractions of light are commonly used in physics and optics to describe how light interacts with different materials and surfaces.
Reflection
There is no particular term. This is because the reflectivity of a surface varies across the electromagnetic spectrum so a surface which reflects a large proportion of blue wavelengths in sunlight may or may not reflect a similar proportion of red wavelengths.
An absorptance is a ratio measuring absorbed radiation and incident radiation - to show how well a particular surface absorbs radiation.
Yes, clouds can reflect incoming solar radiation due to their high albedo, which is the measure of how much sunlight is reflected off a surface. This reflection can have a cooling effect on the Earth's surface by reducing the amount of solar radiation that reaches it.
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
The answer varies from one surface to another. A highly polished mirror will reflect almost all whereas a rough black body will reflect very little.
Radiation can bounce off surfaces such as metal, mirrors, and other reflective materials. The ability of a material to reflect radiation depends on its composition and surface finish. Smooth and polished surfaces tend to reflect radiation more effectively than rough or absorbent surfaces.
For IR, visible, and UV radiation; any shiny surface will do. For acoustic radiation, any massive smooth surface will do. For em radiation, any material with a very different dielectric constant from that of air will do. For ionizing radiation, there is a lot of money to be made from this discovery. That problem is yet (mainly) to be solved.
Black surfaces absorb and emit more radiation across a wider range of wavelengths compared to white surfaces, which reflect more radiation. This difference in absorption and emission rates leads to black surfaces becoming hotter than white surfaces when exposed to radiation.
The fraction of total radiation reflected by a surface is known as its albedo. It is expressed as a value between 0 and 1, with higher values indicating greater reflectivity and lower values indicating lower reflectivity.
Albedo refers to the reflectivity of a surface. Surfaces with high albedo reflect more solar radiation back into space, which can cool the Earth's surface and lower temperatures. Surfaces with low albedo absorb more solar radiation, leading to warming of the Earth's surface.
A smooth, shiny surface such as a mirror is the best reflector of radiation as it can bounce light rays off it without absorbing or scattering them. Rough or dark surfaces tend to absorb more radiation than they reflect.
