PLantea y explica brevemente la ecuacion que rige el efecto fotoelectrico. Indica el significado de cada termino

Explanation:

The photoelectric effect occurs when there is electromagnetic radiation incident on the surface of a metal; if the frequency of the radiation is high enough, electrons are emitted from the surface of the metal.

The equation that describes this effect, described for the first time by Einstein, is:

where:

is the energy of one photon of the incoming radiation, where

is the Planck constant

f is the frequency of the photon

is the work function of the metal, which is the minimum energy required to extract electrons from its surface

is the maximum kinetic energy of the emitted electrons

Looking at the formula we observe that:

- The minimum frequency at which electrons are emitted is found by requiring , so we have

where is called threshold frequency. Therefore, electrons are emitted from the metal's surface only if .

- In the equation the intensity of the light does not appear. This means that if the frequency of the radiation is lower than the threshold frequency, no electrons will be emitted, no matter if we increase the intensity of the radiation.

the answer is a. at the equator
