RAMAN EFFECT OF BENZENE AND TOLUENE UNDER HIGH. Prism Resolving Power. The term resolving power is applied to spectrographic devices using a prism or a grating. Resolving power signifies the ability of the instrument to form separate spectral images of two neighbouring wavelengths, λ and λ + dλ in the wavelength region λ., Brief derivations of dispersion and resolving power give their expression in terms of the directly measurable angle of the prism and its angle of deviation at different wavelengths. Elimination of the length of the prism base seems to improve student understanding of the quantities. Students' experimental results are given to show the precision.
