standard position a, b, and c they can be varied in width till the prism appears white. In the following equations an expression like " 106 " means a slit width of 10 at standard position b. An equation may thus be formed immediately from experiment; iS-6a + 31-46 + 30-5^ = white (i) One of the… … Fig. 56. — Clerk Maxwell's Curves We have expressed the composition of the unknown c' in terms of the necessary slit- widths of the standards for its formation. The colours selected by Maxwell for the standards corresponded to wave-lengths -63 /x (red), -528 fx (green), and -457 ^ (blue). His…
