### the quantum world

What are the units/conversions we should know when talking about wavelength, frequency and energy?

We should know how to express wavelength in terms of nanometers as well as meters. With regard to frequency, we need to know the unit of 1 Hertz, equivalent to second^-1. We should also know how to express energy in joules as well as in kilojoules.

also, some problems start in (for example) milligrams or picometers. make sure you convert them to grams/meters before you begin.
