Light (therefore electron) is both a particle (a discrete package) and wave (continuous) at same time. So you can say that if you know Energy of light, you know frequency and wavelength of light. This will be used in the explanation of how atoms interact with energy.

Properties: continuous and can't break it up into smaller parts | Properties: comes in discrete packages (he called "quanta", basic unit he called "photon", happy now Star Trek geeks) | ||||||
Analogy: Water (is light/energy) being squirted on You: Comes from a garden hose (as a single stream) |
Analogy: Water (is light/energy) being squirted on You: Comes as a water balloon (know how much water coming at you by size of balloon) |

Equation: c = f * lamda c = speed of light (3.00E8 m/s or 3.00E8 m*Hz) f = frequency of light as Hz or 1/s where 1 1/s = 1 Hz lamda (symbol: backwards h, see in example calculations) is wavelength (m or nm) |
Equation (called Planck Equation): E = h*f E - energy of light (in J) h - Planck's constant : 6.60E-34 J/Hz f - frequency of light as Hz or 1/s |
