when photons got enough energy and getting out from that meterial electric current produced from that movement called photo electric.
Light.
yes alkali metals are suitable for photo electric emission
Photo electric emisson or photo electric effect
Photo electrons. So current due to these photo electrons is named as photo electric current.
photo electric transducer
The photo-electric effect is the ability of light to cause the movement of electrons, which is called an electric current.
photo electric effect,compton's effect
photo electric effect,compton's effect
Smoke alarms typically use photo-electric sensors or alpha-particle emitters, although the photo-electric sensors are much better for detecting smoldering fires.
At present, the current price range for electric photo frames is anything from 50$ and more. The price very much depends on the memory the photo frame has.
A photo-electric cell responds to light by giving an electric output, it is not for illuminating anything
it was for photo electric effect ~_~
By using photo electric emission phenomenon.
