PIRA Code(s): 5C30.40 Set up time:5 minutes Operation: Jars can be charged with either the Wimshurst generator (5A50.10) or Van de Graaf generator (5A50.30). Charge Leyden jars in parallel and discharge, charge in parallel again and connect in series before discharging. The intensity of the sparks as well as their duration is much greater for the series connection. Physics and Science Concepts: Electricity and Magnetism, Capacitance Safety: Do not touch the charged capacitor. Make sure the jar is discharged before storing or touching.
PIRA Code(s): 6A20.45 Set up time:none Operation: Use the different types of mirrors to compare reflection. Physics and Science Concepts: Geometrical Optics, Reflection Safety: Do not shine bright light into mirror.
PIRA Code(s): 6A40.99 Set up time:none Operation: Shine a focused beam of light at one of the facets of the prism. Light is refracted and split into its constituent wavelengths (i.e. Colors of the rainbow). These can be used with various other optical experiments. Physics and Science Concepts: Optics, Refraction Safety: Edges and corners may be sharp
PIRA Code(s): 6D30.10 Set up time:none Operation: Shine light through the rings so that they are reflected onto a wall. An overhead is good for this. Turn the screws on the frame to change the interference pattern. Physics and Science Concepts: Interference Safety: Over head projector may be obtained from demo 9A36.10.
