Measurement in this study has mainly been carried out by colorimetrical method. In the next place, the experimental formula concerning the velocity of ageing and that of 1/τλ²o = aλo - b (τ: turbidity, λo: wavelength in water, a, b: constants.) have been obtained with satisfactory accuracy, where radii R(nm) of the particles have been calculated from a or b of the above formula in the range of 26~70 (nm), and the R agree with the results from Rayleigh's formula in case of less than 40 nm., Article, 信州大学教養部紀要. 第二部, 自然科学 7: 9-21(1973)}, pages = {9--21}, title = {AN OPTICAL STUDY ON THE AGEING OF SILVER IODIDE COLLOIDAL SOLUTION}, volume = {7}, year = {1973} }
