100% Correct Answers
Photon - 🧠 ANSWER ✔✔A discrete unit or package of light energy
Photoelectric Effect - 🧠 ANSWER ✔✔The emission of electrons from a
metal when electromagnetic radiation of high enough frequency falls on the
surface
Threshold Frequency (f₀) - 🧠 ANSWER ✔✔The minimum frequency of light
needed to eject electrons from a metal surface
Work Function (Φ) - 🧠 ANSWER ✔✔The minimum energy needed to eject
electrons from the surface of a metal
Millikan's Stopping Potential Experiment - 🧠 ANSWER ✔✔An experiment
utilizing reverse voltage raised to such a level (stopping potential Vs) that it
stops all emitted photoelectrons (NOTE: This experiment is used to test the
Einstein model of the explaining the photoelectric effect.)
