Unlock the mysteries of the Photoelectric Effect with our easy-to-use calculator. Accurately determine photon energy, work function, and maximum electron kinetic energy. Ideal for students, educators, and physicists exploring quantum phenomena!
Formula:
The core principle of the Photoelectric Effect is governed by Einstein's Photoelectric Equation:
Kmax = E - Φ
Where:
- Kmax = Maximum Kinetic Energy of the ejected electron (Joules or electron Volts)
- E = Energy of the incident photon (Joules or electron Volts)
- Φ = Work Function of the material (Joules or electron Volts)
Other key relationships include:
- Photon Energy (E) = hf = hc/λ
- Work Function (Φ) = hf0 = hc/λ0
Constants used in calculations:
- h (Planck's constant) ≈ 6.626 x 10-34 J·s
- c (Speed of light) ≈ 2.998 x 108 m/s
- e (Elementary charge) ≈ 1.602 x 10-19 J/eV
