Term
 converging lens (oval)
Definition
 1. parallel to converging axis, then through focal point on other side2. straight through optical axis (center of lens)3. through close focus, then parallel to optical axis
Term
 can be extended
Definition
 lens
Term
 can't be extended
Definition
 mirror
Term
 diverging lens (concave weird shape)
Definition
 1. straight through optical axis2. parallel to optical axis, then up to where same side focal line would be3. towards far focal point, then parallel to optical axis
Term
 concave mirror (converging, bump facing away)
Definition
 1. parallel to optical axis, then bounces back through same side focus2. towards optical axis then bounces at same angle3. through radius, then bounces straight back
Term
 convex mirror (diverging, bouncing off bump)
Definition
 1. parallel to optical axis, then bounces off where focus line would be2. headed towards radius, bounces off same3. towards optical axis, then away at same angle
Term
 big n
Definition
 slower (water greater than air)
Term
 light enters a new medium where n is bigger
Definition
 light bends towards normal
Term
 light enters a new medium where n is less
Definition
 light refracts away from normal
Term
 small angles (looking into a pool)
Definition
 tanO=sinO
Term
 focal length +/- (converging vs. diverging)
Definition
 c = +, d = -.
Term
 Object distance +/-
Definition
 object on side of lens that light's coming from = +, all the rest = -.
Term
 Image distance +/-
Definition
 image on opposite side of lens from light (real) = +, same side (virtual) = -
Term
 height +/1
Definition
 positive if upright, negative if inverted. (innitial height always positive)
Term
 thin film interference
Definition
 2T=m(+1/2?) x gimmel (gimmel is actually gimmel / n, and bright = + 1/2, dark = just m, minimum thickness = m = 1?)
Term
 double slit interference equations and variables
Definition
 mgimmel = d sin theta, m gimmel = d (x/L) m = number of slits, gimmel = wavelength, d = distance between slits, x = distance between the diffraction pattern, L is distance from slits to wall
Term
 photoelectric effect
Definition
 hf = h x binding frequency + kinetic energy
