Summary
| Description |
English: Various methods have been adopted for studying the effect of mixing colours. Method of Reflection (Lambert).—Place a red wafer on b in figure and a blue wafer on d, and so angle a small glass plate a as to transmit to the eye a reflection of the blue wafer on d in the same line as the rays transmitted from the red wafer on b. The sensation will be that of purple; and by using wafers of different colours, many experiments may thus be performed. |
