Spectrometer, Advanced
- Vernier reading to 30 seconds of arc. The 175 mm diam. scale is fixed. The table and telescope movements are completely independent of each other and read to 30 seconds of arc using double-ended verniers and magnifiers. Both rotations have fine adjustment screws. Coarse adjustments can also be made by the release of the clamping screw. The collimator is mounted…

Speed of a Bubble Set
- The set consists of three rugged, sealed, transparent plastic tubes containing colored fluids of three different viscosities. The bubble in each tube rises at a constant speed which depends on the type of fluid, the angle at which the tube is inclined, and to some extent the temperature. Students track the time it takes for an air bubble to move…
