- the light scattering ability of titanium oxide depends on the relationship between the particle diameter and the wavelength of light. Mie scattering occurs when the particle size of fine titanium oxide is approximately the same as the wavelength of light, and becomes maximum near 1Z2 of the wavelength. If the particle size is even smaller (wavelength of about 1Z10 or less), the light scattering is Rayleigh Scattering, and its scattering power decreases in inverse proportion to the fourth power of the wavelength.
