How would I find the threshold frequency if the work function is 3.33eV?
I know how to calculate minimum frequency.
I know how to calculate minimum frequency.
Threshold frequency is the minimum frequency of light required to eject an electron from a metal surface. It is determined by the work function of the metal.
Threshold frequency is calculated using the formula f0 = W/h, where f0 is the threshold frequency, W is the work function, and h is Planck's constant.
3.33eV is the approximate work function of most metals. It is used as a standard value in the calculation of threshold frequency.
Work function is the minimum amount of energy required to remove an electron from the surface of a metal. It is measured in electron volts (eV) and is unique to each metal.
The photoelectric effect is the emission of electrons from a metal surface when exposed to light of sufficient energy. Threshold frequency is the minimum frequency of light required for this effect to occur. If the frequency of the light is below the threshold frequency, no electrons will be emitted regardless of the intensity of the light.
