### Re: Photoelectric Effect

The photoelectric effect is the emission of electrons from a material due to the shining of a light.

### Re: Photoelectric Effect

When light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. The photoelectric effect did not produce the results they expected but rather supports the view that radiation consists of photons that behave like particles. Basically, it says that if the energy of a photon is less than the energy required to remove an electron then an electron will not be ejected regardless of the intensity of the radiation.

The book defines photoelectric effect as "the emission of electrons from the surface of a metal when electromagnetic radiation strikes it."

The photoelectric effect is the emission of electrons caused by the threshold of the metal and the energy of the photon.

The photoelectric effect is a measurement of how much kinetic energy (or electrons) is released when a photon hits a metal surface. It calculates threshold and if the frequency of the photon is large enough(meaning it is larger than the threshold) to release electrons.

### Re: Photoelectric Effect

The photoelectric effect is the emission of electrons from the radiation of a light that is greater than the threshold energy. It showed that intensity does not affect the ejection of light, but that one photon interacts with one electron.

### Re: Photoelectric Effect

The photoelectric effect is a metal surface that emits electrons when light is shun upon it. In order to solve a problem like this you can use the equation: Ephoton- Work Function= Ekinetic.
Work Function= property of the metal surface
Ephoton: if not given use equations (E=hv; c=wavelength*frequency; E=hc/wavelength)
Ekinetic: Ek=1/2mv^2
