opTHICCs Flashcards
what is visible light?
a form of energy that is visible to the human eye, a very small part of the electromagnetic spectrum
ROY G BIV
what is the electromagnetic spectrum?
the range of frequencies of radiation and their respective wavelengths
what is the e-LEK-tro-mag-NET-ik SPEK-truhm?
its more than just a name of a range of radiataion let me tell you what they are; radiio waves, mircowaves, infrared radiation! visible light! ultra violet, x-rays, gamma rays!!
what are the three categories of matter?
translucent, transparent, and o-PAYK
what is transparent matter
transmits all or almost all light like a clear window
what is translucent matter
transmits some light but absorbs the rest, can not be seen through clearly like a frosted glass window
what is opaque matter
a door, a bike, that paper, all of it . does not transmit any light.
what is luminescent
a source that produces its own light like a lit match
what is non- luminous
does not produce its own light like most things like a pencil, see that water bottle, yep that too.
what is incandescence
light as a result of high temps like molten glass
what is electric discharge
neon light, light produced by passing electricity through our frineds the noble gasses
what is phosphorescence
light produced by absorbing UV light like the glow in the dark stars that i once put on my ceiling but i wasnt that into it and the stars were really big and i only put like three and it was really bad.
what is florescence
immediate emission of visible light as a result of absorbed UV light like a highlighter
what is this chemiluminescence
the direct production of light due to a chemical reaction like when you crack glow sticks little to no heat produced
bioluminescence is
production of light in living organisims like fireflies
