No. Kinetic Energy of a photon depends only on the frequency of the light (or in other words frequency of the photons which the light comprises of).
Intensity of light, on the other hand, is a way to talk about how many photons are there in, say, a beam of light (putting it in simple words)!
No, the kinetic energy of a photoelectron is primarily determined by the frequency of the incident light (photon energy), not the intensity of the light. Increasing the intensity of light will increase the number of photoelectrons emitted but will not change their individual kinetic energies.

What is the measure of intensity of heat in degrees reflecting the average kinetic energy of the molecules?
The measure of intensity of heat in degrees reflecting the average kinetic energy of the molecules is temperature. Temperature is a quantitative measure of the average kinetic energy of the particles in a substance or system. The higher the temperature, the greater the average kinetic energy of the molecules.
Is total energy of revolving electron in an atom zero?
In the classical picture, the total energy of a revolving electron in an atom is not zero as it has both kinetic and potential energy. However, in the quantum mechanical model, the energy of an electron in an atom is quantized and can only take on specific discrete values governed by the principles of quantum mechanics.
What does kinetic energy depend on in addition to speed?
Kinetic energy can be expressed by the equation: Ek= ½ mv2. Therefore in addition to speed (v), kinetic energy is also dependent on mass (m).
What physical factors does the average kinetic energy of molecules depend on?
The average kinetic energy of molecules depends on temperature, which is a measure of the average kinetic energy of the particles in a substance. The kinetic energy of molecules is also affected by their mass and velocity. Temperature and molecular mass have a direct relationship with kinetic energy, while velocity has an indirect relationship.
What is the total energy of a revolving electron in an atom?
The total energy of a revolving electron in an atom is the sum of its kinetic energy and potential energy. The kinetic energy is due to its motion, while the potential energy is associated with its attraction to the nucleus via electrostatic forces. The total energy is negative, indicating that the electron is bound to the atom.
When an electron is ejected from the surface what type of energy does the electron possess?
The ejected electron possesses kinetic energy as it moves away from the surface.
What is the measure of intensity of heat in degrees reflecting the average kinetic energy of the molecules?
The measure of intensity of heat in degrees reflecting the average kinetic energy of the molecules is temperature. Temperature is a quantitative measure of the average kinetic energy of the particles in a substance or system. The higher the temperature, the greater the average kinetic energy of the molecules.
what factors of the kinetic energy of a body depend on?
The kinetic energy of a body depends on its mass and its velocity. As the mass of the body increases, its kinetic energy also increases. Similarly, as the velocity of the body increases, its kinetic energy increases as well.
What does a vehicle's momentum depend on?
Kinetic Energy
What does the amount of kinetic energy of a moving object depend?
The kinetic energy depends on the object's mass, and on its speed.
Is total energy of revolving electron in an atom zero?
In the classical picture, the total energy of a revolving electron in an atom is not zero as it has both kinetic and potential energy. However, in the quantum mechanical model, the energy of an electron in an atom is quantized and can only take on specific discrete values governed by the principles of quantum mechanics.
Which factor provides kinetic energy of an electron?
The factor that provides kinetic energy to an electron is the difference in potential energy between the electron's initial and final states. This energy can arise from sources such as electric fields, magnetic fields, or interactions with other particles.
What is more- potential energy or kinetic energy of an electron in hydrogen atom?
Both are equal.
This is the measure of intensity of heat in degress reflecting the average kinetic energy of the moleness?
Temperature is the measure of intensity of heat in degrees, reflecting the average kinetic energy of the molecules in a substance. The higher the temperature, the faster the molecules move, and the more kinetic energy they possess. Temperature is typically measured in degrees Celsius or Fahrenheit.
What 2 things does an object kinetic energy depend on?
An object's kinetic energy depends on its mass and its velocity. As an object's mass or velocity increases, its kinetic energy will also increase.
What factors does the kinetic energy of a body depend on?
The kinetic energy of a body depends on its mass and its velocity. The kinetic energy of an object increases with its mass and also increases with the square of its velocity.
In the Photoelectric effect after the threshold frequency what effect does the increased frequency have on the photocurrent If you assume the Intensity of the source to be constant?
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
