Photoelectric Effect Calculator – Find Kinetic Energy & Work Function

Share This Post & Help Others!

Calculate photon energy, work function, maximum kinetic energy, and velocity of emitted electrons with this interactive Photoelectric Effect Calculator.

Photoelectric Effect Calculator

Incident Light
Metal Properties
Emitted Electron

Check our examples:

  • Example 1 – Sodium (2.3 eV) hit by Violet Light (400 nm)
  • Example 2 – Zinc (4.3 eV) hit by UV Light (250 nm)
  • Example 3 – Copper (4.7 eV) hit by deep UV (200 nm)
Note: If the photon energy is less than the work function, no electrons are emitted (Kinetic Energy & Velocity will be 0).
