What is an actinograph?
An actinograph is a recording actinometer, a device used to measure the heating power of electromagnetic radiation.
What is electronic pollution?
Some people believe that electromagnetic radiation from power lines and electric devices can impact human health. This is largely unproven.
Should electromagnetic radiation be avoided at all cost?
No mainly because it is impossible. The electromagnetic spectrum is everywhere visible light is a small part of it as are radio waves. It isn't a bad idea to avoid some of it X rays, ultraviolet light, microwaves etc. are potentially harmful hence the issue with cell phones high tension power cables etc.
Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
Do Gamma ray burst form a black hole?
In an indirect way, yes. Gama rays are the highest-intensity form of electromagnetic energy. They usually indicate a very power energy source. Most black holes are formed by exploding stars called supernovas. These events can be detected as gamma ray bursts.
How thermal energy is transferred by radiation?
Radiation is the transfer of energy by electromagnetic waves. Considering the dual nature of electromagnetic radiation, you could also consider it to be transferred by photons of the electromagnetic radiation. The rate of transfer of radiation is given by the surface area of the radiation source, the surface area of the object receiving the radiation, a geometric coefficient accounting for how much of the radiation from the source actually hits the receiving object, a physical constant called the Stephan-Boltzman constant, the reflectivity, transparency, and absorbtivity of the receiving object for the wavelengths of the radiated energy, and the difference in the 4th power of the thermodynamic temperatures of the objects.
What is the power source of a solar cell?
The sun. Energy in the form of electromagnetic radiation excites electrons in the solar cell and is transformed into electrical energy.
Which type of energy travels in waves?
An electromagnetic wave, such as light.An electromagnetic wave, such as light.An electromagnetic wave, such as light.An electromagnetic wave, such as light.
What is an actinometer?
An actinometer is a device used to maesure the heating power of electromagnetic radiation.
What is sunlight's energy called?
Sunlight is electromagnetic radiation often referred to as solar power.
What is an actinograph?
An actinograph is a recording actinometer, a device used to measure the heating power of electromagnetic radiation.
Gamma rays have?
Gamma rays are electromagnetic radiation. Gamma rays have very high penetration power. But they have low kinetic power and ionizing power.
What is an actinogram?
An actinogram is a record produced by an actinograph, a machine used to measure the heating power of electromagnetic radiation.
What form of energy is the most common on earth?
Wind energy, solar power and hydrolicpower
Can electromagnetic energy move a model car?
If it has a battery that is electromagnetic energy, but if you mean radiation force you need 300 megawatts of power for 1 Newton force.
What determines the frequency of an electromagnetic wave?
The frequency of the source that produced the wave.
What type of electromagnetic wave has the shortest wavelenght?
Gamma rays have the shortest wavelength compared to most of other electromagnetic radiation. Gamma rays have high penetrating power and are high in frequency. Exposure to this type of radiation can cause many health complications.
