  4. This scientist won a Nobel prize for explaining the photoelectric effect.

  5. Who was Albert Einstein?

  6. This refers to the radiation an object emits because of its temperature.

  7. What is blackbody radiation?

  8. This German scientist was the first to “quantize” energy.

  9. Who was Max Planck?

  10. It’s the work function of a metal that absorbs 4 eV photons and emits electrons with a maximum 1 eV kinetic energy.

  11. What is 3eV?

  12. This constant of nature is the slope of a graph of KEMAX vs. frequency.

  13. What is Planck’s Constant (h)?

  14. It’s the force of attraction between electrons and protons.

  15. What is the electric force (electromagnetic force)?

  16. Of red or blue, this color of light will have a longer wavelength.

  17. What is red?

  18. This type of spectrum is produced when excited electrons drop back down to lower levels.

  19. What is an emission spectrum?

  20. It’s how many transitions (from higher to lower) are possible in an atom with only four energy levels.

  21. What is six?

  22. This spectrum is also called a black-line spectrum.

  23. What is an absorption spectrum?

  24. This equation shows the equivalence of mass and energy.

  25. What is E=mc2?

  26. This force holds the nucleons together in the nucleus.

  27. What is the strong nuclear force?

  28. It’s the name for a version of an atom that has the same number of protons but a different number of neutrons.

  29. What is an isotope?

  30. It’s the mass a particle has when it has no kinetic or potential energy.

  31. What is rest mass?

  32. It’s how much energy would be needed to separate a nucleus into individual particles.

  33. What is binding energy?

  34. This Polish physicist won two Nobel Prizes for her work with radioactivity.

  35. Who was Marie Curie?

  36. This happens when smaller nuclei join to form larger nuclei.

  37. What is nuclear fusion?

  38. This type of radioactivity releases helium nuclei.

  39. What is alpha decay?

  40. This process is used to determine the approximate age of ancient plants and animals.

  41. What is carbon dating?

  42. This force is responsible for the beta decay of some larger nuclei.

  43. What is the weak nuclear force?

  44. This method of heat transfer requires the motion of a fluid.

  45. What is convection?

  46. This method of heat transfer requires contact between two objects.

  47. What is conduction?

  48. The Law of Conservation of Energy is also given this thermodynamic name.

  49. What is the First Law of Thermodynamics?

  50. According to this principle, no process can ever be 100 % efficient.
