The energy of a photon is related to its?
... frequency of the electromagnetic radiation of which the photon is a particle.
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 matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
After the absorption, the matter has added energy equal to 'hf' the energy of the absorbed photon.
What is threshold frequency?
Threshold frequency (fo) is minimum frequency at which electrons are ejected from a metal.
What is the energy in a photon of light proportional to?
The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
An electron gains 5.5 x 10-16 J of energy when a photon is absorbed What is the frequency of the photon that is absorbed?
8.3 x 1017 Hz

What does the electron produce when they change energy levels?
a photon is emitted or absorbed

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 happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
What does the change of an atom from an excited state to the ground state always require?
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.
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
A photon with frequency 2.1 x 1014 Hz strikes an atom and is absorbed by the atom What statement is correct about this event?
An electron in the atom gains 1.4 x 10-19 J of energy.
What is threshold frequency?
Threshold frequency (fo) is minimum frequency at which electrons are ejected from a metal.
What is the energy in a photon of light proportional to?
The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
