what is the relationship between frequency and kinetic energy max ?
The photoelectric effect is a phenomenon in which electrons are ejected from a material when it is exposed to light of a certain frequency or above. This effect was first described by Albert Einstein and is a fundamental concept in quantum physics.
The photoelectric effect is one of the key experiments that led to the development of quantum physics. It demonstrated that light has both wave-like and particle-like properties, and that the energy of a light particle (photon) is directly proportional to its frequency.
The work function is the minimum amount of energy required for an electron to be ejected from a material during the photoelectric effect. It is a material-specific property and is dependent on the type of material and its surface conditions.
The photoelectric effect has many applications in technology, such as in photovoltaic solar panels, photomultiplier tubes, and photocells used in light sensors. It is also used in electron microscopy and spectroscopy techniques to study the properties of materials.
The photoelectric effect was one of the first experiments that showed the particle-like nature of light and provided evidence for the existence of photons. It also helped to establish the concept of energy quantization, which is a fundamental principle in quantum physics.
