Dispersion (from 8.2) Flashcards
1
Q
speed if light in a VACUUM…
A
is constant for all wavelengths
2
Q
in mediums other than a vacuum…
A
different wavelengths travel at different speeds
3
Q
dispersion
A
when various wavelengths of light separate from each other
4
Q
what CHANGES when a wavelength enters a medium with a difference index of refraction?
A
the WAVELENGTH changes
5
Q
what DOES NOT CHANGE when a wavelength enters a medium with a difference index of refraction?
A
the FREQUENCY stays the same
6
Q
chromatic aberration
A
the failure of a spherical lens to focus all colors to the same point due to dispersion
