July 17th Flashcards
polychromatic light vs monochromatic light
polychromatic- light waves with different wave lengths- white light
monochromatic- only one colour
why does thin-oil interference generate multicoloured array when 2 semitransparent fluids are used (water sitting on oil)
the thickness of the top fluid varies along the fluid interface
- constructive and destructive interference among waveforms of polychromatic light
undermines complacency
undermines- erodes the foundation, lessens the effectiveness of
complacency- feeling smug or uncritical satisfaction with oneself or ones achivments
-feeling pleasure of security, often while unaware of some potencial danger
a complacent attitude
too satisfied with yourself in a situation, so that any change is unnessasry
pragmatic
dealing with things sensibly and realistically in a way that is based on practical rather than theoretical considerations
sentiment
an opinion, view, feeling, attitude
when James said there was no such thing as “the religious sentiment” he meant
no one attitude
he was more openminded, leading his to conclude that there are many vible religious perspectives!
pluralistic
relating to or advocating a system in which multiple states, groups, principles, ideas, sources of authority can coexist
- in philosophy, pluralistic approach is one that recognizes that there is more than one ultimate principle
empiricist
a person who supports the theory that all knowledge is based on experience derived from the senses
what do empiricist believe
Empiricism is a philosophical belief that states your knowledge of the world is based on your experiences, particularly your sensory experiences. According to empiricists, our learning is based on our observations and perception; knowledge is not possible without experience.
subordinate
lower in rank or importance
myr-i-ad (mere-i-ad)
extremely great number
trigonal planar vs trigonal pyramid
planar - has 3 sigma bonds- no lone pairs (120)
pyramid - 3 sigma and one lone pair at the top - basically similar to tetrahedral but one of the bonds is a lone pair)
watts (power)
J/s
joules
N x m
what are all waves on the spectrum
electromagnetic
which are low f and long? whats their energy like
long radio waves - lower energy bc E= hf - low f = low energy
red or violet lower f
violet high f (400nm) –> red longer
