Blackbody
Blackbodies.
This radiation can be called protonic.
Insolation is intercepted solar radiation.
The ozone layer protects us from the radiation of sun. This radiation is called ultraviolet radiation and is very harmful.
Heat waves traveling at the speed of light are called RADIATION! :)
Any object that can specifically absorb and emit radiation (in the form of, say, infrared radiation), is called a selective absorbers. An example is: Snow. It is a good absorber of infrared radiation but poor absorber of sunligh. Object that selectively absorb radiation at some wavelength tend to radiate radiation at that same wavelength. CO2 and water vapors are both very good absorber of infrared radiation but at the same time poor absorber of different forms of solar radiation that are visible to us.
Blackbodies.
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.
The capacitor is called a bypass capacitor , it provides a low impedence path for AC emitter current to groun.
It is not called that.
The shock absorber between bones is called cartilage.
The shock absorber in the body is called the sacroiliac joint. The joint is located on top of the sacrum near the base of the spinal column.
It is not. You have something confused.
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
A matt black surface is best. A theoretical perfect radiator is called a black body.

yes, heat radiation is called infrared radiation
