If this limit is exceeded the effect is proportional to the light intensity at constant frequency. Similar behaviour occurs in the ionisation of gas molecules and the so-called ionisation potential may be calculated, provided that the frequency of the light capable of ionising the gas is known.

To use this online calculator for Threshold Frequency in Photo Electric Effect, enter Work function of the surface of the metal (phi) and hit the calculate button. Here is how the Threshold Frequency in Photo Electric Effect calculation can be explained with given input values -> 1.509E+33 = 1/[hP] .

He used a vacuumed glass tube with two electrodes and a window allowing light to shine on the cathode surface. Using an adjustable Solar-powered calculators are hand-held electronic calculators powered by solar cells mounted on the device. They were introduced at the end of the 1970s. Amorphous silicon has been used as a photovoltaic solar cell material for devices which require very little power, such as pocket calculators, because their lower performance compared to conventional crystalline silicon solar cells is more A photon particle is the tiny blob of pure energy. Under suitable circumstances, we can use light to push electrons and free them from the surface of a solid. This process is termed as the photoelectric effect or photoelectric emission.

Work Function or Threshold Energy (Φ) If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a photon), you get hv=pc. Because wavelength (λ) is c / v, the equation can be simplified to p = h / λ, so a photon has momentum even though it has zero rest mass. 2 comments.
