Variable Angle Glass Prism, 5° x 5° x 170° Material_Cork six convex/concave lenses spanning 10-50cm

six convex/concave lenses spanning 10-50cm focal lengths

Right-triangle 30° x 60° x 90° glass prism

this center-zero galvanometer reads 35-0-35mV at 1mV per division on a fully enclosed EDM-80 housing

The topics covered on this board include: Airbag construction and operation

Eight nickel-plated aluminum forks spanning C 256Hz to C 512Hz in a C-major scale

Variable Angle Glass Prism, 5° x 5° x 170° Material_Cork six convex/concave lenses spanning 10-50cmGlass prism with a 5 degree apex and 5 x 5 x 170 angles, the shallow apex producing minimal deviation for studying small angle approximation in dispersion experiments.
