When an electron is displaced in a semiconductor the hole thats left behind is what?
When an electron is displaced in a semiconductor, the hole that is left behind is called an electron hole. Energy can still be conducted because other electrons can and do jump to the space left by a displaced electron.
What can be emmited from radioactive decay?
Many particles can be emitted from radioactive decay. We have Internal Conversion in which a nucleus transfers the energy to an electron which then releases it. There is also Isometric Transition which is basically the gamma ray (photon). There is the decay in which a nucleon is emitted. In this scenario we can have an alpha decay (in which an alpha particle decays), a proton emission, a neutron emission, double proton emission (two protons are emitted), spontaneous fission (the nucleus brakes down into two smaller nuclei and/or other particles) and we have the cluster decay (where the nucleus emits a smaller nucleus). There is the beta decay too. There is the Beta decay (electron and electron antineutrino are emitted), positron emission (a positron and an electron neutrino are emitted), electron capture (an electron is captured by the nucleus and a neutrino is emitted), bound state beta decay (the nucleus decays to an electron and an antineutrino but here the electron is not emitted since it is captured into a K-shell), double beta decay (two electrons and two antineutrinos are emitted), double electron capture (the nucleus absorbs two electrons and emits two neutrinos), electron capture with positron emission (an electron is absorbed and a positron is emitted along with two neutrinos), and double positron emission (in which the nucleus emits two positrons and two neutrons).
Why Did electron music start?
There is no such thing as "electron music". ----------------------------- If you are referring to Electronic; it originated in the 80's with artists experimenting with it. It became popular and other categories such as Trance branched to it.
What does the process in which an unstable atomic nucleus emits charged particles or energy or both?
In the process of radioactive decay an unstable atomic nucleus emits energy to get closer to a state of stability. Whether this energy is emitted in particles, electromagnetic radiation, or both depends on which decay paths are available to the nucleus and which decay paths are forbidden to the nucleus by Quantum Mechanics.Some of the decay processes are:alpha - energy is released in the momentum of the ejected alpha particle (helium nucleus)beta - energy is released in the momentum of the ejected electron or positron (and the hard to detect neutrino)gamma - energy is released as electromagnetic radiation (gamma ray photon)spontaneous fission - energy is released in the momentum of the ejected fission product atoms and the ejected neutrons
What 3 things are produced during nuclear decay?
The energy can be viewed as thermal, kinetic, electrical, or electromagnetic. But at the atomic and subatomic level, these are often viewed as much the same. What one person might call a fast neutron, another might call a hot neutron. The measurement could be in degrees Celsius, or in kilometers per second. But it is usually in electron volts. This applies not only to the particles or waves emitted, but to the daughter atoms.
If an electron vibrates up and down 1000 times each second it generates an electromagnetic wave having a?
Frequency of 1000 Hz. (Wavelength of 300 kilometers.)
How does frequency of a wave compare with the frequency of the source?
The frequency of a wave is the same as the frequency of the source that produces it. The frequency of a wave is determined by the frequency of the vibrating source that creates it, so they are directly related.
Why electron cannot be accelerated by cyclotron?
In a cyclotron, the most important condition is that of the cyclotron frequency. The frequency of the square wave oscillator connected to the dees of the cyclotron must match the frequency of revolution of the charged particle being accelerated. For ordinary ions, once the frequency is set there is no need to change or adjust the frequency. The equation for cyclotron frequency is As it is clear from the above equation that the cyclotron frequency is inversely proportional to mass of the ion. The frequency of revolution is apparently constant for ordinary ions. If an electron is accelerated in a cyclotron, it quickly picks up high-speed comparable to the speed of light because of its light mass. The speed comparable to the speed of light is called relativistic speed. At relativistic speeds, mass is not constant but varies according to the relation. As per the equation as speed increases, relativistic mass increases. This will change the frequency of revolution and the revolution will go out of phase. The acceleration will stop.
What effect does an electromagnetic field have on an electron?
An electromagnetic field can exert a force on an electron, causing it to accelerate or move in a specific direction. The direction and magnitude of the force depend on the strength and orientation of the electromagnetic field.
If the electron in a hydrogen atom obeyed classical mechanics instead of quantum mechanics would it emit a continuous spectrum or a line spectrum?
In some text books on physical chemistry it is stated that if an electron followed the classical laws of mechanics it would continue to emit energy in the form of electromagnetic radiation until it fell to the nucleus. It is not sensible to consider the spectrum of emitted electromagnetic radiation because its wavelength is a function of the Schrodinger equation under the influence of the Hamilton operator. So my only have desecrate values. A classical picture of the atom would not obey the Schrodinger equation so there is no way of predicting the way it would emit energy.
What small objects generate electromagnetic radiation?
Electron release electromagnetic radiation when they lose energy.
What are the functions of the electromagnetic lenses?
Electromagnetic lenses are used in electron microscopes to focus and manipulate electron beams. They can bend the path of electrons and control the focal point to provide detailed imaging of samples. Electromagnetic lenses are crucial for achieving high resolution and magnification in electron microscopy.
What determines the frequency of electromagnetic waves?
An EM wave is caused by an energy source, such as something as big as a supernova or something as small as an electron changing in speed. I would say the change in the energy level of the energetic particle that causes the wave determines the frequency of the wave. +++ Whilst you may be right about the quantum physics, the frequency of the wave is that of the energy source, be it in a star or a radio transmitter, driving it.
How can you find the frequency of gamma radiation when given the mega electron volts?
To find the frequency of gamma radiation from mega electron volts, you can use the equation E = h*f, where E is the energy in electron volts, h is Planck's constant, and f is the frequency. By converting mega electron volts to electron volts and rearranging the equation, you can solve for the frequency.
What is plasma frequency?
The plasma frequency,(5)is the most fundamental time-scale in plasma physics. Clearly, there is a different plasma frequency for each species. However, the relatively fast electron frequency is, by far, the most important, and references to ``the plasma frequency'' in text-books invariably mean the electron plasma frequency.
In the Photoelectric effect after the threshold frequency what effect does the increased frequency have on the photocurrent If you assume the Intensity of the source to be constant?
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
Which of the following is a lens found on electron microscopes but not on light microscopes?
An electromagnetic lens is found on electron microscopes but not on light microscopes. Electromagnetic lenses use magnetic fields to focus electron beams in electron microscopes, allowing for higher magnification and resolution compared to light microscopes.
