| Pregunta | Respuesta |
| Threshold frequency explanation? | Minimum frequency that needs to illuminate a metal surface for photoELECTRONS to be emitted |
| Formula for energy of a photon? | E=hf (= Planck's constant*frequency) |
| Threshold frequency formula? | Threshold frequency=Φ/h (= work functions/planck's constant) |
| Formula for energy levels within any atom? | En= [Z²/n² * -13.6ev ] (Z is number of protons in atom's nucleus, n is energy level number) |
| Energy of an emitted photon formula? | Energy of emitted photon = E₂-E₁ (=Energy level higher- Energy level lower) |
| deBrolglie wavelength formula | λ=h/p (where p= MOMENTUM=mΔv, and h is planck's constant) |
| Binding energy formula | Ebinding= Δm * c² (= (Δm)c²) |
| energy in a reaction q formula? | Q= [(mass of A + mass of B) - (mass of C + mass of D)] c² (where A+B-->C+D) |
| Relativistic formula for velocity | Vstationary obj.= [u+v] / [1 + uv/c²] (where u is velocity of large object, and v is velocity of "thrown" object relative to large object) |
| Relativistic formula for time | ΔTstationary= Y (ΔTmoving) |
