Various shadows show straight line propagation of light. Also, Green and red lights shine through a single hole into a dark room. The colored lights shine on the wall in the dark room with the colors reversed. A girl wearing a green hat and red dress casts an inverted image on the wall inside the dark room as in a pinhole camera. |

| 6A10.150 | Deck Prism | In the days before electricity, light below a vessel's deck was provided by canles, oil and kerosene lamps. All dangerous aboard a wooden ship. A clever solution for the lighting problem was the deck prism. Laid flush into the deck, small conical prisms drew light down below decks without weakening the deck planks. This solid, poured-glass prism is an exact replica of a prism taken from the Charles W. Morgan, a 19th century New England whaling ship. |
