Very visual resolve relations between Index of refraction and Positive or Negative optical elements. Many and differing examples show the exploitation of optical elements in technical optics /concave lenses, plano-concave lenses, convex and plano-convex lenses, equilateral prisms, right angled prisms, mirrors, condenser lenses, cube beamsplitters and periscopes, Very interesting experiments using air lenses illustrate why optical elements can be positive or negative depending on the Index of refraction. Kaasas ingliskeelsed katsejuhendid koos skeemide ja valemitega ning näidisvideod.
