Term
diverging lens (concave weird shape) |
|
Definition
1. straight through optical axis 2. parallel to optical axis, then up to where same side focal line would be 3. 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 focus 2. towards optical axis then bounces at same angle 3. 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 be 2. headed towards radius, bounces off same 3. towards optical axis, then away at same angle |

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) |

|
|
Term
focal length +/- (converging vs. diverging) |

Definition
|
|
Term
|
Definition
object on side of lens that light's coming from = +, all the rest = -. |
|
|
Term
|
Definition
image on opposite side of lens from light (real) = +, same side (virtual) = - |

Term
|
Definition
positive if upright, negative if inverted. (innitial height always positive) |

|
Term
|
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 |
