When excited electrons radiate energy the amount of energy given off is equal to?
The amount of energy given off by excited electrons when they radiate energy is equal to the difference in energy level between the initial and final states. This emitted energy is typically in the form of photons.
When the electrons of an excited atom fall back to lower levels there is an emission of energy that produces what?
When the electrons of an excited atom fall back to lower levels, they emit energy in the form of photons. These photons can have specific frequencies corresponding to the energy difference between the initial and final electron energy levels, leading to the emission of light in various forms such as visible, ultraviolet, or infrared light.
Which statement best describes the light that will cause emission of electrons from a given metal through the photoelectric effect?
The light must consist of photons with energy equal to or greater than the work function of the metal to cause the emission of electrons through the photoelectric effect. The intensity of the light does not play a significant role in the emission of electrons, only the energy of individual photons matters.
What happens when electrons return to ground state?
When electrons return to the ground state, they emit energy in the form of photons. This energy is released in the form of light, typically in the visible spectrum. This process is known as emitting or releasing photons.
When electrons jump to a higher energy level they emit or absorb energy?
Electrons are normally in an energy level called the ground state. In the ground state electrons absorb heat energy and then get into the excited state where they release the energy and exert light energy. The light energy can be seen with a spectroscope with a unique bright line emission spectrum.
Why does uranium shine when exposed to bright light?
The electrons when switch to next higher orbit they need energy to do it they do it by using energy of photons when the photons have equal energy to that required by electron theY absorb it,similarly when the are spelled out the yield out of uranium then they are accelerated to such speed that they emit their energy in showing a spectrum.

When electrons of an excited atom falls back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.

Use Einstein photoelectric equation to explain Why for a particular metal electrons are emitted only when the frequency of the incident radiation is greater than a certain value?
The photoelectric effect occurs when photons with sufficient energy strike a metal surface, causing electrons to be emitted. According to the Einstein photoelectric equation, the energy of the emitted electron is equal to the energy of the incident photon minus the work function of the metal. Therefore, only photons with energy greater than the work function of the metal can overcome the binding energy of the electrons and cause emission. This is why electrons are emitted only when the frequency (or energy) of the incident radiation is greater than a certain value.
What is the effect of frequency of incident light on photoelectric current?
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.
When electrons jump to a higher energy level they emit or absorb energy?
Electrons are normally in an energy level called the ground state. In the ground state electrons absorb heat energy and then get into the excited state where they release the energy and exert light energy. The light energy can be seen with a spectroscope with a unique bright line emission spectrum.
When 10 electrons drop from fifth to second energy level?
When 10 electrons drop from the fifth to the second energy level, energy in the form of photons is emitted. The energy of the emitted photon is equal to the difference in energy levels between the initial and final states of the electrons. This process is known as photon emission or de-excitation.
What gives electron their speed?
Photons that are absorbed by the electrons. Speed is changed by an exchange of momentum, which is equal to the mass times velocity (with regards to electrons, at least - photons are massless and their momentum works a bit differently.) Since electrons have such a tiny mass, it doesn't take much to make it go very, very fast.
In atoms what energy is equal numbers of electrons and protons there is a?
In atoms, the energy associated with having equal numbers of protons and electrons is the electric potential energy. This energy arises from the electrostatic attraction between the positively charged protons in the nucleus and the negatively charged electrons in orbit around the nucleus.
