The maximum kinetic energy of ejected electrons begins to decrease because excess energy is transferred to surrounding particles as heat or other forms of energy, reducing the energy available for the electrons. This decrease in kinetic energy can be observed as the voltage applied to the system is increased beyond a certain point, leading to a decrease in the maximum energy of the ejected electrons.
What else can I help you with?
If molybdenum is irradiated with light of a wavelength of 122 nm what is the maximum possible kinetic energy of the emitted electrons?
The maximum kinetic energy of the emitted electrons is calculated using the formula: (E_k = hf - \phi), where (h) is the Planck constant, (f) is the frequency of the light (speed of light/wavelength), and (\phi) is the work function of molybdenum. Given the wavelength, you can calculate the frequency, then use the work function value for molybdenum to find the maximum kinetic energy of the emitted electrons.
Why the kinetic energy of the emitted electrons varies up to a maximum value?
Let the work function of a metal be W. Let C be a constant of the dimension of energy. if Kis the maximum kinetic energy of an electron then.......W=C-K..... (K HERE IS THE ENERGY SUPLIED BY A PHOTON TO THE ELECTRON)
When a ball is throw to straight up into the air. at what position it is kinetic energy at its maximu?
The ball will have maximum kinetic energy at the moment that it is released from the thrower's hand, as it is moving fastest at this point. As the ball travels upward, its kinetic energy will gradually decrease and be converted into potential energy due to the force of gravity acting against it.
Which letter shows the ball when it has the maximum kinetic energy?
The letter showing the ball when it has the maximum kinetic energy is likely the one where the ball is moving the fastest. This is typically when it is at the lowest point in its trajectory due to the maximum potential energy being converted into kinetic energy.

The maximum number of electrons in a single d subshell is 10.
When a clean surface of potassium metal is exposed to blue light electrons are emitted if the intensity of the blue light is increased what will also increase?
i have the same question on my test haha for me, the answers are: a) The number of electrons ejected per second b) the maximum kinetic energy of the ejected electrons c) the threshold frequency of the ejected electrons d) the time lag between the absorption of blue light and the start of emission of the electrons e) none of these A the number of electrons ejected per second,,,,, correct answer
What is the relationship between maximum frequency and maximum kinetic energy in photoelectric effect?
In the photoelectric effect, the maximum kinetic energy of emitted electrons is directly related to the frequency of the incident light. According to Einstein's photoelectric equation, the maximum kinetic energy (K.E.) of the electrons is given by ( K.E. = hf - \phi ), where ( h ) is Planck's constant, ( f ) is the frequency of the light, and ( \phi ) is the work function of the material. As the frequency increases, the maximum kinetic energy of the emitted electrons also increases, provided the frequency exceeds the threshold frequency necessary to release electrons. Thus, higher frequencies lead to greater maximum kinetic energies of the emitted electrons.

When a metal was exposed to light at a frequency of 3.91 1015 electrons were emitted with a kinetic energy of 3.40 101 J. What is the maximum number of electrons that could be ejected from this me?
To determine the maximum number of electrons that can be ejected from the metal, we first need to find the work function (ϕ) using the photoelectric equation (E_k = hf - \phi), where (E_k) is the kinetic energy of the emitted electrons, (h) is Planck's constant ((6.626 \times 10^{-34} , \text{Js})), and (f) is the frequency of the light. Calculating the energy of the incident photons: [ E = hf = (6.626 \times 10^{-34} , \text{Js}) \times (3.91 \times 10^{15} , \text{s}^{-1}) \approx 2.59 \times 10^{-18} , \text{J} ] Next, we can find the work function: [ \phi = hf - E_k = 2.59 \times 10^{-18} , \text{J} - 3.40 \times 10^{-19} , \text{J} \approx 2.25 \times 10^{-18} , \text{J} ] The maximum number of electrons emitted depends on the total energy supplied and the work function, but without further information on the total energy input, we cannot calculate the exact maximum number of electrons that can be ejected.
