Hand-Painted 3D Starfish Sectional Anatomical Model on Base, 18 x 16 inch Light & Optics_Spectroscopy Graphite lattice kit whose atoms

Graphite lattice kit whose atoms and connecting rods assemble into planar carbon sheets

with both 4mm stackable sockets and screw terminals so leads wire in without an adapter to either bench standard

exposing the longitudinal and transverse components of wave motion mechanically

Labeled-terminal 50-ohm resistance unit at 7

Used to produce concentric Newton's rings under monochromatic light
