Chapter 7 and 8 Flashcards
What is Diffraction?
Light (any waves) will spread out through small holes/slits and around corners.
What do diffraction lines tell us?
The specific elements that are present
In a double-slit experiment, what is the overlap called?
Interference
what pattern is created from the double-slit?
Fringe pattern
What does the Fringe pattern tell us?
Some places constructively interfere while other places will destructively interfere.
Constructive Interference
When to sine waves going in the same rhythm combine to create a larger sine wave.
Destructive Interference
When two sine waves going opposite connect and flatten out the wave.
What happens to electrons when too much energy is created?
Ionization
Do electrons want to be excited?
No
What is the process of electrons loosing energy called?
Recombination and Cascade
