The following experiment tells us that this is the beginning of the danger. Solar cells convert solar energy into electrical energy through the photoelectric effect.

In 1905, Einstein found the photoelectric effect on the basis of quantum theory. According to Einstein, when a photon of energy hν falls on the metal surface it transfers all its energy to the electron of the metal and the electron is emitted out from the metal surface. This phenomenon is called the photoelectric effect.

The effect has found use in electronic devices specialized for light detection and precisely timed electron emission. The experimental results Photoelectric effect experiment. Metals have a ‘sea’ of free electrons. It is these spare electrons which are able to be dislodged by passing photons, provided that the photon has sufficient energy.

In this experiment, shining light upon a metal surface may cause electrons to be emitted from the metal. In 1905, Albert Einstein working in a 30 Dec 2020 What was measured in Millikan's study of the Photoelectric Effect? D. R. Lloyd. School of Chemistry, Trinity College, Dublin, Ireland.

The basic physical process underlying this effect is the emission of electrons in metals exposed to light. Experiment 14 ~ The Photoelectric Effect Objective: In this experiment you will demonstrate that light can behave as a particle and also determine Planck’s constant. Equipment: Photoelectric apparatus with a phototube, Light Emitting Diodes (LEDs) of several colors, and two digital meters. Theory: Photoelectric effect Explaining the experiments on the photoelectric effect. How these experiments led to the idea of light behaving as a particle of energy called a photon.

The metal plate in the photodiode is illuminated with various frequencies of light, selected from a mercury lamp using filters. The photoelectric effect happens when particles of light, called photons, hit a metal. Electrons hanging on to the outside of the metal can get knocked off if the photons hit them hard enough (that is, with enough energy). The photoelectric effect At the turn of the century, physicists who experimented with electricity had noticed something about the interaction of light, metals, and electric current.

The photoelectric effect was first introduced by Wilhelm Ludwig Franz Hallwachs in the year 1887 and the experimental verification was done by Heinrich Rudolf Hertz. They observed that when a surface is exposed to electromagnetic radiation at a higher threshold frequency, the radiation is absorbed and the electrons are emitted.
