What happens to the energy of a photon when it strikes matter?
A. It turns into heat
B.It turns into electrical energy
C. The matter emits electrons
D. All of the above
Answers
It is converted into electrical energy.
Kinetic energy: W=E
W = work function.
E stands for photon energy.
The photoelectric effect is the process by which electrons are released from the surface of a metal when a sufficient frequency of light is incident on it. The term "photon" or "quanta" refers to the energy carried by each light particle, depending on how the frequency of light is described.
E = hν
where,
E is the energy of a photon or light particle.
Planck's constant is H. Planck's constant has a value of 6.62611034Js.
= Frequency of light
The process of removing an electron from a metal atom consumes some energy, and the remaining energy is transferred as kinetic energy to the ejected electron. When they collide, the electrons that have been ejected from beneath the surface of the metal retain little of their kinetic energy. The surface of the photon, which has the greatest kinetic energy, contains the electrons carrying all the kinetic energy.
By adding the energy required to remove the electron and the maximum kinetic energy of the electron, we can mathematically quantify the energy of the photon.
∴E=W+KE
We are aware of that
E = hν,
h=W+KE.
∴KE=hν−W

Answer:
Explanation:
The energy is changed into electrical energy.
W=E for kinetic energy
Workfunction W
E is the letter for photon energy.
The photoelectric effect is the mechanism by which, when a high enough frequency of light is incident on a metal, electrons are released from its surface. Depending on how the frequency of light is represented, each light particle's energy is referred to as a "photon" or "quanta."
E = hv
where,
E is a photon or light particle's energy.
H stands for Planck's constant, and its value is 6.62611034Js.
Light-frequency =
Some energy is used to eject an electron from a metal atom, and any remaining energy is given to the ejected electron as kinetic energy.
The expelled electrons from beneath the metal's surface have lost most of their kinetic energy when they collide. The electrons carrying all of the kinetic energy are located on the photon's surface, which also has the most of it.
We can calculate the energy of the photon quantitatively by summing the energy needed to remove the electron and the electron's maximum kinetic energy.
∴E=W+KE
We are conscious of that
E = hv,
h=W+KE.
∴
KE=hν−W
