Diffraction Grating Flashcards
1
Q
Path Difference
A
Divide of light source so that separates rays of light create different paths
Difference in path causes a phase difference
2
Q
Gratings
A
Flat arrays of regularly spaced lines, which are designed to break up a plane wave-front into a set of separate wave sources
3
Q
Emission Spectra
A
Light (emissions) created by electrons heated or by an electric discharge moving up an energy level
Flame test used to identify elements
4
Q
Phase Difference
A
When the point on one wave lags behind the exact same point on another wave
Expressed as an angle in either degrees or radians
