What is the best colour for radiation absorption?
hi
Do thermal curtains stop conduction convection or radiation?
best answer it is a worm
What are the best absorbers of thermal radiation?
Black, dull surfaces are the best absorbers of thermal radiation because the heat doesn't reflect off it unlike shiny surfaces.
Would have the best thermal insulation properties?
A thick mug.
What would be an example of a good thermal conductor?
Graphene is the best thermal conductor. Any metal or metallic objects such as a frying pan would be a good thermal conductor, including diamond.

between white and silver surfaces, which one is the best emitter of radiation?
The best emitter of radiation depends on the type of radiation you are referring to. Generally, when discussing thermal radiation, a "blackbody" is considered the best emitter. A blackbody is an idealized object that absorbs all incident radiation and emits radiation perfectly according to its temperature. In real-world scenarios, there is a concept called "emissivity," which quantifies how effectively an object emits thermal radiation compared to a blackbody at the same temperature. The emissivity of an object ranges between 0 and 1, with 1 being a perfect blackbody. Regarding white and silver surfaces: White surfaces: White surfaces tend to have high reflectivity and low emissivity. This means they are good at reflecting incoming radiation and do not emit thermal radiation as effectively. In terms of thermal radiation emission, they are not the best emitters. Silver surfaces: Silver surfaces also have high reflectivity but generally have higher emissivity compared to white surfaces. They emit more thermal radiation than white surfaces, but they are still not as effective emitters as a perfect blackbody. In conclusion, between white and silver surfaces, silver surfaces would be the better emitter of thermal radiation due to their higher emissivity. However, neither of them is as efficient as a blackbody emitter. Keep in mind that the exact emissivity values can vary based on the specific properties and conditions of the materials used.

What is the transfer of energy by electromagnetic waves?
The transfer of energy by electromagnetic waves is called electromagnetic radiation. Light, radio waves and X-rays are a few other examples of this radiation phenomenon. The Transfer process is the "flow" of particles from one location to another. The best visual example is the transfer of "heat" from one source to another.

Do all objects equally conduct absorb emit heat?
The emitting and absorbtion of heat is related to ' thermal radiation', whereas the 'conduction' of heat is a separate topic in physics. Firstly, thermal radiation is not equivalent across all substances. Darker coloured 'objects' such as those with a 'matt black' colour are the best emitters and absorbers of 'heat'. Lighter silvered 'objects' are the poorest emitters, the poorest absorbers, and the best reflectors of heat. Similarly, not all objects equally conduct heat. Metals are the best conductors of heat; and so non-metals are the worst. All Insulators do not conduct heat. Examples of good insulators are: plastic and wood.
How would radiation be used at the airport?
because Danielle is the best :)
Why doesn't thermal radiation need a medium to transfer heat energy?
Thermal energy is an electromagnetic wave, as light is. Light (and other electromagnetic waves) travel best through empty space. They consist of an electric and magnetic field, that propagates as a wave.
Where can one get a cheap thermal vest?
A thermal vest is a wonderful investment, especially if you enjoy the outdoors. The best place to find a cheap thermal vest would be an auction website such as eBay or Amazon.
