How xrays produced?
Xrays are produced by stopping fast moving electrons by allowing it to bombard on a target. The kinetic energy 1/2 m v2 is changed into hv, here h is Planck's constant and v is the frequency of Xradiation Energy can neither be created nor be destroyed but could be changed from one form to the other So electrostatic potential energy ----> kinetic energy ------> photon energy Well, actually no. X-rays are actually powerful penetrating waves that can seep into anything soft, such as skin, and be absorbed by hard things, such as bones or metal. Though, if the doctor or dentist, etc. didn't put a large thing of lead around your neck, the X-rays would eventually kill you.
How photons are generated by reverse photelectric effect?
In the reverse photoelectric effect, electrons are accelerated through a potential difference and strike a metal target, resulting in the production of photons. The kinetic energy of the incident electrons is converted into electromagnetic radiation when they hit the target, creating photons with energy corresponding to the kinetic energy of the electrons. This phenomenon is the basis for X-ray generation in X-ray tubes.
In the photoelectric effect what happens when lighthits the metal?
When light hits a metal in the photoelectric effect, it can transfer its energy to the electrons in the metal. If the energy of the light is high enough, it can cause the electrons to be ejected from the metal, creating a flow of electrical current.
What happens when light hits metal?
When light hits metal, the atoms in the metal absorb the energy from the light. This causes the electrons in the metal to become excited and jump to higher energy levels. The electrons may then re-emit the absorbed energy as light if they return to their original energy levels, a phenomenon known as reflection.
What happens to electrons in the photo electric effect?
Electrons are ejected from a metal surface when it is exposed to light of sufficient energy. This phenomenon is known as the photoelectric effect. The energy of the incident light is absorbed by the electrons, causing them to be emitted from the metal surface.
If you shoot very high energy electrons at a metal target can you make x-rays?
Yes

What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface

Where does x ray come from?
The energy to generate X-rays for medical imaging comes from high voltage. High voltage is applied to an X-ray tube to accelerate electrons across the space between the anode and cathode in the tube. The higher the voltage, the more the electrons are accelerated. The electrons slam into the cathode, which is a metal target. This "knocks loose" some electrons in the metallic crystal structure of the metal of the cathode, and when the electrons that have been slammed into give up energy to return to a "relaxed" state, they give off very high energy electromagnetic radiation - X-rays.
Why schottky is called hot carrier diode?
Because the energy of electrons transfer from semiconductor to metal side have more energy than the fermi energy of electrons in metal side. That's why these are called hot carrier diodes
Explain How a metal conducts thermal energy?
Metals conduct thermal energy through the movement of free electrons. When heat is applied, the free electrons gain kinetic energy and move through the metal, colliding with lattice vibrations and transferring their energy. This process allows thermal energy to be rapidly transferred through the metal.
Which type of energy is most transported through metal wires?
Electricity, in the form of electrons, is the most common type of energy that is transported through metal wires. Metal wires are excellent conductors of electricity due to the ability of metals to easily allow the flow of electrons.
What occurs when light strikes a metal and electrons are released?
When light strikes a metal, it transfers energy to the electrons in the metal, causing them to be ejected in a process known as photoelectric effect. These ejected electrons are called photoelectrons and can be used in applications such as photovoltaic cells and photoemission spectroscopy. The energy of the ejected electrons is proportional to the frequency of the incident light.
