path length same = constructive interference, bright

 

path length different (halve wavelength out) = destructive interference dark

coherent sources produce waves with the same phase relationship (always iin or out of phase by a certain amount)

nodal lines = no disturbance/dark

blue light is scattered, ,: sky is blue (Rayleigh scattering)

*collects light*

*keeps it in a mirror lined box*

*brings it out to play on rainy days*

Portable rainbow machine :)

hot object --> continuous spectrum (lightbulb)

 

hot gas/largevoltage --> line emmision spectrum (neon lights)

 

hot object through cold gas --> line absorption spectrum (sun)

*keeps it in a mirror lined box*

 

*pulls faces at all the other mirror-mes*

Pop pop pop pop pop pop pop pop pop pop pop

Limes

light can cuase electrons to be emitted from metals

 

only above threashold frequency (work function)

Infinite dinys

increasing energy past work function = more kinetic energy

 

increasing intensity = greater current (more photoelectrons emitted)

Hey, that one blinked >.>

I wonder what it would be like to be in a box like that

wave theory of light cannot adequately explain photoelectric effect (though diffraction shows light is a wave) so light is also a particle

Hm there's a horizon program about diny DNA or something now...

I wonder what it would be like to be in a box like that

 

dark or light, but always getting dimmer

I like kaleidoscopes

I wish I knew where mine had gone

Aw baby dinosaurs

I want one
