The energy of an ejected electron during the photoelectric effect depends on which of the following?
A The speed of the photon interacting with the electron
B The frequency of the light illuminating the metal
C The intensity of light illuminating the metal
D The charge of the electron​

Respuesta :

Answer:Frequency of the light illuminating the metal.

Explanation:

option A:

The photons are light particles.Their speed is always constant.So,their speed does not affect the energy of the ejected electron.

option B:

The energy of the photon is given by [tex]hf[/tex] where [tex]h[/tex] is Plancks constant and [tex]f[/tex] is frequency.

The energy of the photon converts to the energy of the emitted electron.

So,when the frequency of the photon is higher,the energy of the emitted electron increases.

option C:

The intensity of light does not have any effect on energy of the electron emitted.The intensity only determines the number of photo electrons emitted.

option D:

The charge of the electron is a constant always.So,their charge does not affect the energy of the ejected electron.

Answer:

B. The frequency of the light illuminating the metal.
