Term
 find v for wave
Definition
 v=λ/f
Term
 Energy of photon=
Definition
 E=hf or E=hc/λ
Term
 c=
Definition
 3 X10^8
Term
 light, electric field, magnetic field
Definition
 all orthogonal (90*) from each other
Term
 electromagnetic spectrome, compare E,f,λ
Definition
 if E increase, f increases, but λ decreasesE↑ f↑ λ ↓
Term
 highest to lowest energy waves
Definition
Term
 longest wave length
Definition
Term
 visible light longest wave length
Definition
 red
Term
 visible light highest energy
Definition
 violet
Term
 vis light order
Definition
 ROYGBIV
Term
 law of REFLECTION
Definition
 angle of incidence= angle of reflection
Term
 Law of refraction
Definition
 Snells lawn1sinθ1=n2sinθ2
Term
 1 photon of light has energy= 5how much does 2 photons have? have much does 1 mol of photons have?
Definition
 multiply by 2or avogadro's number to find a mol
Term
 index of refraction, n=
Definition
 n= c/v
Term
 changing from medium to medium, f
Definition
 frequency never changes, but wavelength can
Term
 total internal reflection
Definition
 sin θcrit= n2/n1
Term
 what is total internal reflection?
Definition
 when the angle of incidence causes an angle of refraction to be = or greater than 90 sin90=1, thus sinθ2 cancels out.
Term
 total internal reflection only happens when light is going
Definition
 from higher n to lower n
Term
 going from lower n to higher n the angle of refraction is __
Definition
 smaller, bends toward the normal
Term
 going from larger n to smaller n the angle of refraction will be
Definition
 larger, bend away from normal
Term
 dispersion
Definition
 the index of refraction is different for different wavelengths. travel at diff speeds and get refracted diff angles.
Term
 dispersion of decreased λ
Definition
 d λ increased n decreased angle refraction
Term
 if the angle of incidence of a flashlight into a lake =60 what is the angle of reflection? (n air=1, n water=1.33)
Definition
 60REFLECTION incidence=reflection
