18/10/2010 · Update: concerning the photoelectric effect. i know how to calculate threshold frequency, but i'm stuck here. please help thanks... 21/08/2014 · For the first part calculate the wavelength corresponding to an energy of 2 eV using the second formula (E=hc/lambda), the work function is the minimum energy to cause electron emission, so the result of this calculation is the threshold wavelength.

17/09/2008 · Best Answer: The threshold frequency f0 is the light frequency whose photon energy = the work function of the metal being measured. The work function phi (φ) is the minimum photon energy required for photoelectric-effect emission of electrons from the metal. φ = hf0, where h is Planck's constant, thus f0...
This is the threshold frequency. It's the frequency of the photon that just has enough energy to equal the work function. So the equation can be written with ϕ replaced by hf o

Hi, i'm doing my project on hand gesture recognition. And trying to find out the threshold value for segmenting the hand region. Anyone, can you please tell me how to find out the threshold value using histogram based method how to get to corner brook newfoundland The threshold for this element corresponds to a wavelength of 683 nm. Using this wavelength in the Planck relationship gives a photon energy of 1.82 eV. Further analysis. How to find xbox live email address

How To Find Threshold Frequency

This frequency is called the photoelectric threshold frequency. Though all metals exhibit the effect, each metal has its own characteristic threshold frequency. The alkali metals (lithium, sodium, potassium, rubidium, etc.) have the lowest threshold frequencies. For these metals the threshold frequencies are in the range of visible light. For other metals, such as those used in the early

  • This is the established threshold or the softest level that the listener can hear that particular tone. Set the frequency control to 2000 Hz and repeat Steps 2 through 9. Repeat Steps 2 through 9 for test frequencies 4000 Hz and 500 Hz.
