- Photoelectric effect - Wikipedia
The photoelectric effect is the emission of electrons from a material caused by electromagnetic radiation such as ultraviolet light Electrons emitted in this manner are called photoelectrons
- Photoelectric effect | Definition, Examples, Applications | Britannica
Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation The effect is often defined as the ejection of electrons from a metal when light falls on it
- Photoelectric Effect - Science Notes and Projects
The photoelectric effect is the phenomenon in which the surface of a material—typically a metal —ejects electrons when it absorbs electromagnetic radiation, usually in the form of ultraviolet or visible light
- 6. 3: Photoelectric Effect - Physics LibreTexts
When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength (or equivalently, above a threshold frequency), the incident radiation is absorbed and the exposed surface emits electrons This phenomenon is known as the photoelectric effect
- Photoelectric Effect: Definition, Equation and Work Function
The photoelectric effect refers to the phenomenon where light, typically in the form of photons, can cause the emission of electrons from a material’s surface
- Photoelectric effect (article) | Khan Academy
When light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called photoelectrons
- Photoelectric Effect – University Physics Volume 3
When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength (or equivalently, above a threshold frequency), the incident radiation is absorbed and the exposed surface emits electrons This phenomenon is known as the photoelectric effect
- Photoelectric Effect – The Physics Hypertextbook
All electrons are identical to one another in mass, charge, spin, and magnetic moment The photoelectric effect was first observed in 1887 by Heinrich Hertz during experiments with a spark gap generator (the earliest device that could be called a radio)
