Grade 12 Physics: Quantum Mechanics

One question a day, with solutions and a Socratic tutor.

Sample questions

Question 01

A photon with a wavelength of \( 300 \, \text{nm} \) strikes a metal surface and ejects an electron. Calculate the energy of the photon in electron volts (eV). Open question

Question 02

Light photons with energy 8.3 eV strike a metal surface and eject electrons with 4.9 eV of kinetic energy. What is the work function of the metal? Open question

Question 03

According to the classical view, the energy carried in a wave is related to which property of the wave? Open question
