Below is a list of the key ideas involved in the study of quantum physics.
| Electromagnetic radiation consists of small packets of energy |
| These packets of energy are called photons |
| The energy that the photon has depends upon the frequency of the radiation |
| If the frequency increases so does the energy |
| The amount of energy is expressed by this equation E = hf. (E= energy, h = Plank's constant [6.626 x 10-34], f = frequency) |
| This means that ultraviolet photons have more energy than infrared photons |
| If the beam of radiation is increased, the number of photons emitted will increase but the amount of energy that each photon has will not change |
