The threshold frequency is the minimum frequency of light required to eject electrons from a metal surface (photoelectric effect). The work function is the minimum energy needed to remove an electron from the metal surface. The threshold frequency is directly related to the work function through the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency.

Oh, dude, work function and threshold frequency are like distant cousins at a family reunion. Work function is the minimum energy needed to eject an electron from a metal surface, while threshold frequency is the minimum frequency of light required to cause photoelectric emission. So, like, work function is about energy, and threshold frequency is about frequency. They're related, but not like, best friends or anything.
Electrons are emitted from a metal surface when the energy of the incident photons is great enough to overcome the work function of the metal. This minimum energy required is equivalent to a certain threshold frequency, known as the threshold frequency. Electrons can only be emitted when the frequency of the incident radiation is greater than this threshold frequency because lower frequency photons do not possess enough energy to overcome the work function and release electrons from the metal surface.
Threshold frequency refers to the minimum frequency of incident light required to eject electrons from the surface of a metal in the photoelectric effect. Electrons will only be emitted if the frequency of light is equal to or greater than the threshold frequency, as lower frequencies do not possess sufficient energy to overcome the work function of the metal.
Threshold frequency is the minimum frequency of light required to eject electrons from a metal surface in the photoelectric effect. Below this frequency, no electrons are emitted regardless of intensity. It is a characteristic property of each metal and is used to determine the work function of the metal.
The work function of the photoemissive metal.

The threshold frequency for a material can be calculated by dividing the work function of the material by Planck's constant. The work function is the minimum amount of energy needed to release an electron from the material's surface. Planck's constant is a fundamental constant in quantum mechanics. By dividing these two values, you can determine the threshold frequency at which the material will emit electrons when exposed to light.

work function = planck's constant x threshold frequency w=h(ft) it also equals the energy(eV) Planck's constant(h) = 6.626 x 10-34
Einstein used Planck's theory of quantization to explain the photoelectric effect by proposing that light is quantized into packets of energy called photons. These photons have energy proportional to their frequency, and when light with frequency below the threshold frequency interacts with a metal surface, no electrons are emitted. Above the threshold frequency, each photon can transfer enough energy to overcome the work function of the metal, causing electrons to be emitted.
Yes, that is true. This minimum frequency is called the threshold frequency and is determined by the work function of the material. Photons with frequencies lower than the threshold frequency do not carry enough energy to eject electrons from the metal surface, even if the intensity of light is high.
The function of a photoelectric material is the energy that a photon of light must possess to just expel an electron from the surface of a material. The work function of cesium is 3.42 x 10^-19 Joules.Ê
If monochromatic light is shining on an alkali metal and cesium is just above the threshold frequency, electrons in the cesium atoms will be ejected in a process called the photoelectric effect. These ejected electrons will have kinetic energy equal to the difference between the energy of the incident photon and the work function of the metal. The photoelectrons will be emitted instantaneously.
