What else can I help you with?
What are perfect absorbers of radiation called?
Perfect absorbers of radiation are called blackbodies. These are idealized objects that absorb all electromagnetic radiation that falls upon them, without reflecting or transmitting any of it. Blackbodies are efficient at absorbing radiation across a wide range of wavelengths.
What radiation results in the emission of protons?
This radiation can be called protonic.
What is radiotherapy also called?
It is sometimes called radiation therapy, x-ray therapy radiation treatment, cobalt therapy, electron beam therapy, or irradiation
What gas is called the natural shield against the radiation?
Ozone shields against incoming UV radiation
What is most of heating in the troposphere comes from the movement of air called?
it is called radiation
Why are carbon dioxide and water vapor called selective absorbers?
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.
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.

Capacitor from emitter to ground in common emitter circuit is called?
The capacitor is called a bypass capacitor , it provides a low impedence path for AC emitter current to groun.
Why common current is called an emitter follower?
It is not called that.
What acts as a shock absorber between bones?
The shock absorber between bones is called cartilage.
What is the shock absorber in the body called?
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.
Why collector current is called an emitter follower?
It is not. You have something confused.
What do you called a material that reflects and absorb any light that strikes its surface?
A material that reflects and absorbs all light that strikes its surface is called a perfect absorber, or a blackbody. It absorbs all incident light and reflects none, resulting in a black appearance.
Why emitter bias circuit is called self bias circuit?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
What do you called the center element between the emitter and collector in a transistor?
The base.
What is transistor action?
The transistor has three regions, emitter,base and collector. The base is much thinner than the emitter while the collector is wider than both. However for the sake of convenience the emitter and collector are usually shown to be of equal size. The transistor has two pn junctions that means it is like two diodes. The junction between emitter and base may be called emitter-base diode or simply the emitter diode.The junction between base and collector may be called collector-base diode or simply collector diode. The emitter diode is always forward biased and the collector diode is always reverse biased.
