1. hv=hvo + 1/2mvo2

here h= plank's constant

v= cut off wavelength

vo=cut off frequency

m= mass

vo=stopping potential

Who discover photo electric effect and what date?

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.


What is a semiconductor device that produce electric current through the photo-voltaic is an?

A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.


What properties of light cannot be described by using the wave model of light?

The particle nature of light, as described by the photon theory, cannot be fully explained by the wave model of light. The wave model also cannot account for certain phenomena such as the photoelectric effect and the behavior of light in very small scales, which require a particle-like description of light.


What was Albert Einsteins biggest disappointment?

One of Albert Einstein's biggest disappointments was his inability to create a unified field theory that could explain all the fundamental forces of the universe in a single framework. He spent much of his later years pursuing this goal but was ultimately unsuccessful.


What happens to electrons in the photo electric effect?

Electrons are ejected from a metal surface when it is exposed to light of sufficient energy. This phenomenon is known as the photoelectric effect. The energy of the incident light is absorbed by the electrons, causing them to be emitted from the metal surface.

What was einsteins explantation for the photoelctric effect?

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.


Electrons ejected in the photoelectric effect are called?

Photo electrons. So current due to these photo electrons is named as photo electric current.

Some of Albert Einstein's theries of the electric effect?

Einsteinâ??s theories on the photo-electric effect led to the quantum revolution and his winning a Nobel Prize in 1921 for his law of the photoelectric effect. This law stated that the photoelectric effect was the result of light energy being carried in discrete quantized packets.
