Which of the electromagnetic spectrum would produce a photoelectric effect?
Solar
What is a photoelectron?
A photoelectron is an electron emitted from a material when it absorbs energy from light, typically ultraviolet or X-ray radiation. This process is known as the photoelectric effect and is used in various scientific techniques such as photoelectron spectroscopy to analyze the electronic structure of materials.
Which equation was used by Albert Einstein to explain the photoelectric effect?
Einstein used the equation E = hf to explain the photoelectric effect, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the light. This equation shows that the energy of a photon is directly proportional to its frequency.
What was albert einsteins's contribution to our understanding of the photoelectric effect?
He wrote a paper that described the photoelectric effect. The paper contained equations used to explain why certain wavelengths of light cause the p-e effect but others do not and the energy changes in the electrons during the p-e effect.
What are photoelectric cells?
Photoelectric cells are devices that convert light energy into electrical energy. They are commonly used in solar panels to generate electricity from sunlight. The photoelectric effect is the process by which photons in light are absorbed by a material, causing electrons to be emitted and creating an electric current.

Why does the color of the light source determine whether the photoelectric effect will occur?
it doesn't matter how bright the light is in order to break free the electrons from the substrate but the kind of colour used is very important.This is because electron will start to move when light is up close to the blue end of the spectrum.

Why potassium and caesium is rather than lithium are used in photoelectric effect?
Potassium and caesium are more commonly used in photoelectric effect experiments compared to lithium because they have lower work functions, making it easier to release electrons when light is shone on them. This results in a more pronounced and easily measurable photoelectric effect. Additionally, potassium and caesium have larger atomic sizes, which means their electrons are further away from the nucleus, facilitating the ejection of electrons in the photoelectric effect.
What is the difference between photoelectric effect and X-ray?
The photoelectric effect refers to the phenomenon where electrons are emitted from a material when it absorbs photons, typically from ultraviolet or visible light. In contrast, X-rays are a form of high-energy electromagnetic radiation produced when high-speed electrons collide with a target material, resulting in the emission of X-ray photons. While both involve the interaction of light and matter, the photoelectric effect is primarily about electron emission from materials due to lower-energy photons, whereas X-rays are a high-energy form of radiation used in medical imaging and other applications.

Why cesium and potassium used in photoelectric effect?
The ionization enthalpy of K and Cs is less than that of Li and therefore these metals easily lose electrons on exposure to light than lithium.That's the reason potassium and cesium are used in photoelectric cells rather than Cs.

What is the reverse process of photoelectric effect?
reverse process of photo electric effect is done by the supply of electrons or heat to the metal that radiate certain radiation. among them the metals which emit visible radiation are normally used in house hold appliances
Instrument used for changing light to energy?
photo voltaic cells convert light energy to electricalenergy The conversion of sunlight to electricity using photovoltaic (PV) cells, also known as solar cells, is based on the photoelectric effect discovered by Alexander Bequerel in 1839. The photoelectric effect describes the release of positive and negative charge carriers in a solid state when light strikes its surface.
