the energy used by sun to throw electrons (based on thersold frequency) is called work function
Photo electric emisson or photo electric effect
Albert Einstein was awarded the Nobel prize for his work on the photo electric effect.
Just visible light too can be used for photo electric phenomenon. But Hallwachs used UV rays as he used zinc plates. That is all. Moreover the energy of the photon has to be more than the work function of the material being used.
A photo-electric cell responds to light by giving an electric output, it is not for illuminating anything
The particle nature of light
1921 for his work on the photo electric effect
The Nobel Prize for his work on the photo-electric effect.
when photons got enough energy and getting out from that meterial electric current produced from that movement called photo electric.
yes alkali metals are suitable for photo electric emission

Photo electrons. So current due to these photo electrons is named as photo electric current.
photo electric transducer
David William Cornelius has written: 'The study of the velocity of electrons in the photo-electric effect, as a function of the wave-lengths of the light' -- subject(s): Electrons, Radiation
the function of a resister is to lower the voltage.
