Today in class we learned the first lesson of our new unit, electronic structure. We discussed the wave nature of light and how every object has a wave nature. In addition, all waves have a characteristic wave length. Below is a picture of the different parts of a wavelength:

The longer the wavelength, the shorter the amplitude and the lower the energy.
Next, we learned the formula for velocity. Here it is below, showing what each symbol means and the unit that corresponds with each:

C, which is a constant (speed of light= 3.0x10^3) often replaces v in the formula. With at least two parts of the formula, we can solve for any of the pieces of the formula.
