for a photon
energy= Planks Constant * frequency
and
frequency= speed of light/wavelength
so
E= hc/(wavelength)
h= 6.63E-34 J/s
c= 3E8 m/s

One of the more-easily remembered scientific formulas is the one for photon energy:
Energy = (frequency) x (Planck's constant) .
Sadly, the formula is a lot easier to remember than the value of Planck's constant is.
That number is
6.63 x 10^-34 joule-second .
So, for a 170 GHz photon, we have
Energy = (6.63 x 10^-34 joule-second) x (1.7 x 10^11 / second)
= 1.13 x 10^-22 joule .

The line emission spectrum of an atom is caused by the energies released when electrons?
The line emission spectrum of an atom is caused by the energies released when electrons fall from high energy level. It goes down to a low energy level and the extra energy it had from higher level is released as light.
How is spectral analysis used in light sources?
Spectral analysis is a procedure in which a light source is shone through a lens to reveal its components. Light created by different methods have different spectral components, which act like a fingerprint. For example, if you examine the spectrum of a distant star, the different wavelengths will show you what different elements comprise that star. At a more detailed scientific level, the individual lines are determined by the amount of energy lost by a particular atom's electrons as they move between energy levels. Each energy level of an atom's electron shell is characteristic to that atom. When an electron moves from a higher energy level to a lower one, there is a release of energy in the form of a photon, and that photon's wavelength is determined by the amount of energy change, resulting in a spectrographic line characteristic to that atom.
Why do atoms emit only certain wavelengths of light?
The electrons in an atom's "electron shell" all have specific energy levels. If you add energy to an atom, the atom will absorb a specific amount of energy, and the electron will jump up to a higher energy level. Each different element has its own energy levels, and it can only absorb energy in specific amounts. (When you add a lot of energy to the atom, the atom becomes ionized, as one or more electrons absorb enough energy to break free of the atom completely, leaving the atom with an unbalanced positive electrical charge.) When those "excited" or jumped-up electrons release the energy, the electron drops back to its previous level, and the atom (or more specifically, the electron) emits a photon, which is a particle of light. Each photon has a frequency or energy that is distinctive to the element and the energy level. Electrons cannot have intermediate energies; they absorb and release exact "packets" or "quanta" of energy. This is how a mass spectrometer works; the operator ionizes a sample of the material that he wants to analyze, and watches the resulting spectrum. Each wavelength of light emitted by the sample corresponds to one specific element.
Can a solar flashlight be recharged with a light bulb?
Yes, although it will take a lot longer than in sunlight. The particles of light are called photons and each photon carries a certain amount of energy. As the photon hits the photovoltaic cells of the solar panel, the energy they contain is converted into electrical energy by the excitation of electrons in the board. The stronger the light, the more energy.
Why are stars luminous?
Electrons are lazy. They don't want to do any more work than they have to. So, when they're in an atom, they're generally in the lowest possible energy level that they can occupy, called its "ground state," which translates roughly to doing the bare minimum amount of work to get by (I can relate!) But, when you apply some energy to that atom, the electron gets excited and jumps out to a higher energy level. In order to do this, the electron has to absorb some of that energy to get it out there. After a while, the electron decides it's tired of working that hard, and moves back to its ground state where it's supposed to be. At that point, the electron gives back that energy it absorbed in the form of a "photon," a bundle of light energy. Billions and billions of photons make a visible light of a certain wavelength that we can see. This is how neon lights work.
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron
Microwave ovens emit microwave energy with a wavelength of 12.0 cm What is the energy of exactly one photon of this microwave radiation?
A photon of this wavelength has an energy of about 10 ^ -5 eV.
Why is the energy of a photon greater than that of an electron?
It does not. A photon has no rest mass an electron has mass and therefore more energy
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
When an electron drops from a higher energy state to a lower energy state?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?
electron lost 3.6 x 10-19 -barbie=]
Do photon have a greater energy than electron?
No. A photon has no rest mass an electron has mass.
What is the energy of a photon with a frequecy of 1022 Hz?
The photon energy of 1022 Hz is 4.22664452E-12 electron volts.
When sunlight excites electrons how do the electrons change?
Depending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom. If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization. If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light. If the energy of the photon does not fall into one of these categories, the electron does not interact with it. In terms of actually changing the electron, it only changes in energy, not any other property.
