What is the threshold frequency for the photoelectric effect?

Threshold frequency in photoelectric effect is the minimum frequency of electromagnetic radiation which is required for the phenomenon of photoelectric emission to occur from a metal surface. It is a characteristic of electromagnetic radiation (light in case of photoelectric emission) and not metal.

How does threshold frequency depend on intensity of light in photoelectric effect?

how does the threshold frequency depend on intensity of light in photoelectric effect? so, threshold frequency is property f the object not the light. so, threshold frequency of metal does not define the intensity of the light. Yes, for light itself, the intensity is more if frequency is more.

What is the threshold frequency of light?

The threshold frequency is the frequency of light that carries enough energy to dislodge an electron from an atom. This energy is entirely consumed in the process (see References 5). Therefore, the electron gets no kinetic energy at the threshold frequency and it is not released from the atom.

Does the threshold frequency depend on intensity of light?

Threshold frequency is independent of intensity of light in photoelectric effect.

Does threshold frequency depend upon the intensity of light?

What happens to the threshold frequency when the intensity of light is increased?

An increase in the intensity of incoming light that is above the threshold frequency causes the number of electrons that are ejected to increase, but they do not travel any faster.

What is threshold frequency and work function in photoelectric effect?

Threshold Frequency: The threshold frequency is that minimum frequency of light below which the photoelectrons do not emit. Work function: The least energy which can eject the electrons from the surface of the metal.

What is a threshold frequency?

Definition of threshold frequency : the minimum frequency of radiation that will produce a photoelectric effect.

How do you calculate threshold energy?

(E=hv) – threshold energy = (Ek= 1/2me-ve^2) or exactly like the one you posted. Threshold energy is the amount of energy it takes to remove an electron from a metallic surface, just like the work function.

What is photoelectric effect what is the effect of frequency and intensity on photoelectric effect?

1, just the opposite behavior is observed in the photoelectric effect. The intensity affects the number of electrons, and the frequency affects the kinetic energy of the emitted electrons.
