The threshold frequency is defined as the minimum frequency of the incident radiation below which photoelectric emission or emission of electrons is not possible. The threshold frequency refers to the frequency of light that will cause an electron to dislodge emit from the surface of the metal.
Threshold frequency is defined as the minimum frequency that is required for the radiation such that photoelectric effect is produced.
The threshold frequency is defined as the lowest incident radiation frequency below which photoelectric emission is absolutely impossible regardless of the strength of the incident radiation. It can be written as: f = W h here h is Planck's constant, f is threshold frequency, and W is work.
Threshold Frequency & Wavelength. The threshold frequency is defined as: The minimum frequency of incident electromagnetic radiation required to remove a photoelectron from the surface of a metal. The threshold wavelength, related to threshold frequency by the wave equation, is defined as:
The concept of a threshold frequency is required in order to explain why a low frequency source, such as a filament lamp, was unable to liberate any electrons in the gold leaf experiment. The threshold frequency is defined as: The minimum frequency of incident electromagnetic radiation required to remove a photoelectron from the surface of a metal.
2 days ago · 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.
When light of frequency 2.42 X 10^15 Hz is incident on a metal surface, the fastest photoelectrons are found to have a kinetic energy of 1.7eV. Find the threshold frequency of the metal. Let's explore how to use Einstein's photoelectric equation to solve such numerical on photoelectric effect. Created by Mahesh Shenoy.
For a given metal surface, there exists a certain minimum frequency of incident radiation below which no photoelectrons are emitted. This frequency is called the threshold frequency. Increasing the frequency of the incident beam increases the maximum kinetic energy of the emitted photoelectrons, and the stopping voltage has to increase.
Threshold Frequency & Wavelength. The threshold frequency is defined as: The minimum frequency of incident electromagnetic radiation required to remove a photoelectron from the surface of a metal. The threshold wavelength, related to threshold frequency by the wave equation, is defined as:
Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy (K max) of the photoelectrons to the frequency of the absorbed photons (f) and the threshold frequency (f 0) of the photoemissive surface.
