Photon energy
Find energy of a 450 nm photon.
Momentum
Find momentum of that 450 nm photon.
Photoelectric evidence
Why does intensity not affect maximum electron energy?
Einstein equation
Photon energy is 5.0 eV and Φ=2.8 eV. Find stopping potential.
Duality
Give one particle and one wave observation for light.
Matter waves
An electron has p=5.0×10⁻²⁴ kg m s⁻¹. Find λ.
Energy levels
A transition is from −1.5 eV to −4.5 eV. Find emitted photon energy.
Spectrum
Explain why an atom produces lines rather than a continuous spectrum.
