Misalai Photoelectric Emission?

Za mu iya Photoelectric Emission?

Takardun Photoelectric Emission

Photoelectric emission yana nufin fitar da elektronon daga faduwar zafi a lokacin da ciro take shiga.

Hadisi na Quantum

Ciro yana cikin photons, kuma energy ta har photon yana da shugaban hanyar frequency-ri.

 Formula ta Correlation

Amsa E ita ce energy ta photon, h ita ce Planck’s constant, kuma ν ita ce frequency ta ciro.

Work function ta zafi yana da shugaban hanyar chemical makeup da physical structure-ri, kuma yana bambanta a kan zafi. Misali, potassium yana da work function daga 2.3 eV, amma platinum's yana da 6.3 eV.

Photon Energy da Work Function

Don in yi photoelectric emission, energy ta photon ya kamata za su duba da work function ta zafi.

Abubuwan da ke Sake Musu Emission

Frequency ta ciro, intensity ta ciro, da potential difference a kan zafi da anode sun sake musu photoelectric emission.
