Photon energy = (Planck's konstant) x (frequency) nu = E / h E = 2.5 x 10-15 J h = 6.626 x 10-34 J-s nu = (2.5 x 10-15 J) / (6.626 x 10-34 J-s) = (2.5 x 10-15 / 6.626 x 10-34) (J / J - s) = 3.773 x 1019 Hz = 3.773 x 1010 GHz

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.
What does the electron produce when they change energy levels?
a photon is emitted or absorbed
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
When 10 electrons drop from fifth to second energy level?
Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.

Does photoelectric effect take place below threshold frequency?
The threshold frequency for photoelectric emission is the smallest possible frequency a photon can have to be absorbed/emitted by an electron moving between energy levels in an atom. Explanation: Since electrons can't exist /between/ energy levels, and each electron would be moved a very specific amount by any given photon, only photons of certain frequencies can be properly absorbed/emitted, necessitating a minimum frequency.
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=]
When an electron falls from a higher energy level to a lower energy energy level how is the energy released?
The energy is released as electromagetic energy and each transition in each atom has its own wavelength for the light emitted.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
When 10 electrons drop from fifth to second energy level?
Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.
The energy of a photon is related to its?
... frequency of the electromagnetic radiation of which the photon is a particle.
What does incident light that falls on an object do to the electrons in the atoms of an object?
When a photon of energy falls on an electron bound inside an atom, the electron absorbs the energy and is emitted from the atom.
If the photon has a frequency of 4 x 1015 Hz how did the energy of the electron change?
If the change in energy of electron is totally exhibited as a photon then the energy = h times frequency. h = 6.626 x 10 to -34 J s Simply multiply h and frequency you would get the energy in joule
What is threshold frequency?
Threshold frequency (fo) is minimum frequency at which electrons are ejected from a metal.
