STUDY SPEOTEA. 11 to further on. The slit is furnislied with a right-angled reflecting prism, by means of which two spectracan be seen in the field of view at the same time. Thisinstrument can be used for taking the refractive anddispersive powers of solids and liquids if necessary. Fig. 2… … one-prism spectroscope is to be preferred, as it is amplysufficient for the study of the few bright-line spectrawhich have to be studied; and moreover one prism isbetter than two—on account of its small dispersion—in the study of absorption bands. How to observe spectra with the one-prism…
