**resolving**power, the size of the prisms, or their number, is unduly increased. - The optical effect as regards
**resolving**power is the same as with a grating of N lines in the nth order, but, nearly all the light not absorbed by the glass may be concentrated in one or two orders.' - We may say therefore that if the difference between the frequencies n 1 and n, of the two waves is such that in the combined image of the slit the intensity at the minimum between -the two maxima falls to 0.81, the lines are just resolved and n l /(n l n 2) may then be called the
**resolving**power. - Lord Rayleigh's expression for the
**resolving**power of different instruments is based on the assumption that the geometrical image of the slit is narrow compared with the width of the diffraction image. - Unfortunately considerations of luminosity compel the observer often to widen the slit much beyond the range within which the theoretical value of
**resolving**power holds in practice. - We must now however introduce a new criterion the " purity " and distinguish it from the
**resolving**power: the purity is defined by n l /(n l n2), where n 1 and n, are the frequencies of two lines such that they would just be resolved with the width of slit used. - With an indefinitely narrow slit the purity is equal to the
**resolving**power. - As purity and
**resolving**power are essentially positive quantities, n i in the above expression must be the greater of the two frequencies. - If we write P=p R where P denotes the purity and R the
**resolving**power, we may call p the " purityfactor. - The general results may be summarized as follows: if the width of the slit is equal to fX/4D (where X is the wave-length concerned, D the diameter of the collimator lens, and f its focal length) practically full
**resolving**power is obtained and a further narrowing of the slit would lead to loss of light without corresponding gain. - With a slit equal in width to eight times the normal one the purity is reduced to o 45R, so that we lose rather more than half the
**resolving**power and increase the light 3.7 times. - It follows that for observations in which light is a consideration spectroscopes should be used which give about twice the
**resolving**power of that actually required; we may then use a slit having a width of nearly eight times that of the normal one. - Theoretical
**resolving**power can only be obtained when the whole collimator is filled with light and further (as pointed out by Lord Rayleigh in the course of discussion during a meeting of the " Optical Convention " in London, 1905) each portion of the collimator must be illuminated by each portion of the luminous source. - Every observer should not only record the

**resolving**power of a telescope with circular or rectangular aperture is easily investigated experimentally. - A rotation of this amount should therefore be easily visible, but the limits of
**resolving**power are being approached; and the conclusion is independent of the focal length of the mirror, and of the employment of a telescope, provided of course that the reflected image is seen in focus, and that the full width of the mirror is utilized. - We will now consider the important subject of the
**resolving**power of gratings, as dependent upon the number of lines (n) and the order of the spectrum observed (m). - According to our former standard, this gives the smallest difference of wave-lengths in a double line which can be just resolved; and we conclude that the
**resolving**power of a grating depends only upon the total number of lines, and upon the order of the spectrum, without regard to any other considerations. - It is especially to be noticed that the
**resolving**power does not depend directly upon the closeness of the ruling. - There will be destruction by interference of the first, third and odd spectra generally; while the advantage gained in the spectra of even order is not in dispersion, nor in
**resolving**power, but simply in brilliancy, which is increased four times. - If we now suppose half the grating cut away, so as to leave 1000 lines in half an inch, the dispersion will not be altered, while the brightness and
**resolving**power are halved. - There is clearly no theoretical limit to the
**resolving**power of gratings, even in spectra of given order. - But it is possible that, as suggested by Rowland,' the structure of natural spectra may be too coarse to give opportunity for
**resolving**powers much higher than those now in use. - However this may be, it would always be possible, with the aid of a grating of given
**resolving**power, to construct artificially from white light mixtures of slightly different wave-length whose resolution or otherwise would discriminate between powers inferior and superior to the given one.3 2 Compare also F. - In the above discussion it has been supposed that the ruling is accurate, and we have seen that by increase of m a high
