Term
 Reflective index of refraction
Definition
 N¹ sin(θ¹) = N² sin(θ²)   N = index of refraction θ = angle between ray and normal
Term
 N = ____?
Definition
 N= C / V   N = index of refraction C = speed of light V = speed of stuff thru material   *The higher the speed the lower the index of refraction*
Term
 Lens Equation
Definition
 1/dº + 1/d¹ = 1/f   d° = object distance d¹ = image distance f = focal length
Term
 Magnification
Definition
 m = (-d¹ / d°) = (h¹ / h°)   m = magnification d/h ¹ = image distance/ height d/h ° = object distance/height
Term
 finding the focus of a mirror
Definition
 f = R / 2   f = focus  r= center of curvature
Term
 real images have ___
Definition
 a positive image distance a negative image height   a positive object distance a positive object height   a negative magnification
Term
 virtual images have ___
Definition
 a positive magnification   a negative image distance a positive image height   a positive object distance and height
