DISPERSION OF COLOR (P 38 01) Apparatus: GSN 246 POG 465 POG POG 312 POG 490 KAL Adhesive magnetic board Ray box, 6V 20 W Plane mirror for color Prism, glass flint Projection wedge Connecting lead Power supply 1 1 The lamp covered by a mirror for color mixing is set up in the upper left-hand corner of the board The ray of "white" light passes through the optical prism placed directly in front of it In the process the light ray is broken down into the spectral colors, red being refracted the least and violet the most Optics Board Type | SPECTRAL COLORS CANNOT BE FURTHER DISPERSED (P 38 02) Apparatus: GSN 246 POG 465 POG 099.01 POG 312 POG 310.01 POG 490 KAL 60/5A Adhesive magnetic board Ray box, 6V 20 W Plane mirror for color Prism, glass flint Prism, right angle Projection wedge Connecting lead Power supply 1 1 The light is set up in the lower left-hand corner of the board The rays of "white" light are broken down into spectral colors upon passing through the optical prism The edge of a second prism is placed in the rays' path as shown in the figure The individual light rays are partially refracted and partially reflected In neither case can a further dispersion of the spectral colors be observed Spectral colors thus cannot be further dispersed Note: The intensity of the reflected and refracted colors as well as the degree of color saturation can be influenced by rotating the right-angled, equal-sided prism | Optics Board Type CONVERGING SPECTRAL COLORS TO MAKE WHITE (P 38 03) Apparatus: GSN 246 POG 465 POG 099.01 POG 312 POG 240.02 POG 251 POG 490 KAL 60/5A

containing a diaphragm with one slit is set up in the lower left-hand corner of the board A continuous spectrum is generated with the aid of the prism A biconvex lens is formed using the planoconvex lens and the semi-circular model and placed as shown in the figure Upon passing through the convex lens, the spectral colors are combined to form a mixed color When a continuous spectrum enters the lens, the resulting mixed color is white Optics Board Type | MIXED COLOR OF A PARTIAL SPECTRUM (P 38 04) Apparatus: GSN 246 POG 465 POG 099.01 POG 312 POG 240.02 POG 251 POG 490 POF 220.01 KAL 60/5A

Power supply 1 1 1 A lamp containing a diaphragm with one slit is set up in the lower left-hand corner of the board A continuous spectrum is generated with the aid of the optical prism A biconvex lens consisting of a planoconvex lens and a semi-circular model is positioned in the path of the rays as shown in the figure The resulting mixed color is white The spectral colors violet and then the violet-blue area of the spectrum are covered up one after the other with the edge of the slit in the diaphragm The remaining colors refracted by the lens result in a mixed color The experiment may be repeated beginning with red or the slit can be positioned so as to allow only the central area of the spectrum is allowed to pass through | Optics Board Type COMPLEMENTARY COLORS (P 38 05) Apparatus:

Plan-convex, lens model Semicircle, lens model Projection wedge Connecting lead Power supply 1 1 1 1 A continuous spectrum is generated with the aid of the light and the prism A biconvex lens is formed using the planoconvex lens and the semi-circular model, these are arranged as shown in the figure The biconvex lens focuses the spectral colors, resulting in white The right-angled, equal-sided prism is placed between the first prism and the lens for example within the red area of the spectrum as shown in the figure This area of the spectrum is refracted by the prism Two complementary colors result when the rays pass through the lens By moving the prism further into the spectrum, other pairs of complementary colors can be created Note: This experiment may be carried out beginning with the violet end Optics Board Type | SUBTRACTIVE MIXING COLORS (P 38 06) Apparatus: POF 251.01 Color filter disc, Substractive set The three color filters with the subtractive primary colors cyan, magenta and yellow are partially overlapped and held against a bright surface Where the filters overlap, the additive primary colors red, blue and green can be observed | Optics Board Type ADDITIVE MIXING COLORS (P 38 07) Apparatus: GSN 246 POG 465 POF 210 POG 099.01 POG 490 KAL 60/5A Adhesive magnetic Ray box, 6V 20 W Color filter, Aditive Plane mirror for color Projection wedge Connecting lead Power supply 1 The additive color filter is inserted in front of the ray box Use the side that emit divergent ray and projects a divergent light beam in the three additive primary colors red, green and blue Using the three mirrors, the three colored beams are made to overlap on the projection wedge This results in the three subtractive colors cyan, magenta and yellow being produced White results where all three additive colors overlap Optics Board Type |
