|
|
Term
|
Definition
| The number of waves passing a fixed point in one second. |
|
|
Term
| Quantum mechanics addressed the failures of classical mechanics by introducing the concept of wave-particle duality. Why did classical mechanics succeed to explain most of our macroscopic world without this concept? |
|
Definition
| Macroscopic objects can be modeled purely as particles because their wavelenght is so small compared to their scale that it can be neglected for most purposes and still give a good description of their behavior. |

Definition
|
|
Term
True or False
As one obtains the emission spectrum of an atom, electrons must be moving from higher to lower energy levels within the atom. |

Term
| F- is bigger that F because |
|
Definition
| F- has one more electron which causes greater electron repulsions in the outer orbitals, thus expanding the elctron cloud. |
