Webb9 apr. 2024 · In general, the photoelectric effect is the emission of electrons when light is incident on metallic objects. It is broadly classified into two types: the internal photoelectric effect and the external photoelectric effect. The major components of this effect are Planck’s equation, threshold energy, and photoelectric equation.

Webb3 apr. 2024 · One of the important causes of the Photoelectric Effect is the absorption of the light energy by the electrons at the metal surface. The electrons use this light energy to overpower the forces binding them to the nuclei of the metal. The photoelectric effect was discovered by the German physicist Heinrich Rudolf Hertz in 1887.
Webb25 jan. 2024 · Photoelectric Effect: Scientists have been trying to figure out the behaviour of light using its properties to categorize it as a wave or a particle. Light seems to behave as both a particle and wave.
