Bragg equation
Sketch the electromagnetic spectrum, and relatively label the portions that are given various names.
How do x-rays compare to visible light with regard to wavelength and energy. Why do we use them to examine crystals?
Explain the Laue method as it was first used in 1912. What information does it give you?
What are some basic properties of electromagnetic waves?
What wavelengths of X-rays are used to study crystals? Explain how these X-rays are generated in an X-ray tube. What metals are used to generate the X-rays in X-ray equipment?
What kinds of information can one get from powder XRD?
What is the Bragg equation, and what does it tell us?
