False spectra: (a) Rowland ghosts, copper arc lines 5700.24 and 5782.14 A in 3rd order spectrum of grating No. 222. The apparent wave-lengths of the spurious lines may be computed from λ g = ( 1 ± n 3 × 375 ) λ. It is seen that those for n=1 and n=4 are much brighter than the others. (b) Lyman ghosts, spurious infra red lines from strong helium lines in the visible spectrum, 1st order of grating No. 222. The apparent wave-lengths of the first group are approximately 6/5 of 6678.149 while those of the group at the right are about 7/5 of 5875.618A.
