1. hv=hvo + 1/2mvo2
here h= plank's constant
v= cut off wavelength
vo=cut off frequency
m= mass
vo=stopping potential
Photo electric emisson or photo electric effect
Albert Einsteins relativity theory was not accepted during his life time, and only after more experiments were done we are able to accept and appreciate his genius mind! He was awarded Nobel price for photo electric effect and not relativity. please follow my videos if you wish to understand physics more @PhysicsFusion-sm3rt Thank you
The photo electric effect was explained by Einstein in 1905 when he theorized that light could transfer its energy like a particle and knock electrons out of metals. But the actual effect had been observed by a number of scientists since 1887, they just couldn't come up with a satisfactory theory that explained everything they observed. I believe he got the Nobel Prize for his photo electric effect theory, although he is more famous for his Relativity theories.
The particle nature of light
The major applications of photo electric effect are in power satellites, solar cells solar powered calculators, solar cookers etc.

Photo electrons. So current due to these photo electrons is named as photo electric current.
Einstein proposed that light incident on a photo-electric material (indeed, all light), is composed of chunks (he and Max Planck used the term "quanta," the term eventually became "photons"), and that the amount of energy in each chunk was equal to the frequency of the light times Planck's Constant. This explained many puzzling facts about the photo-electric effect, such as (1) why current began to flow almost immediately, even for very low intensity light, (2) why light, no matter how intense, had to be above a certain frequency to get any photo-electric effect, and (3) why higher frequency light resulted in more energetic electrons leaving the material.
it was for photo electric effect ~_~

The photo-electric effect is the ability of light to cause the movement of electrons, which is called an electric current.
1921 for his work on the photo electric effect
photo-electric effect, which is a very obvious manifestation
The Nobel Prize for his work on the photo-electric effect.
