Data Source and Methodology
All calculations are based on the principles outlined in quantum mechanics, specifically the photoelectric effect formula. For more information, refer to the authoritative source: "Quantum Physics for Beginners" by Author Name.
The Formula Explained
The formula used is: \( KE = hf - \phi \)
Where \( KE \) is the kinetic energy of the emitted electron, \( h \) is Planck's constant, \( f \) is the frequency of the incident light, and \( \phi \) is the work function of the material.
Glossary of Terms
- Frequency (f): The number of waves that pass a point per second, measured in Hertz (Hz).
- Work Function (φ): The minimum energy needed to remove an electron from a solid material, measured in electron volts (eV).
- Kinetic Energy (KE): The energy possessed by an electron after being emitted, measured in electron volts (eV).
FAQs
What is the photoelectric effect?
The photoelectric effect is the emission of electrons from a material when light shines on it. It demonstrates the particle nature of light.
How does this calculator work?
This calculator uses the photoelectric effect equation to compute the kinetic energy of emitted electrons based on the input frequency and work function.
