Optical Density: Formula, Features, Transmittance & Absorbance

WebOptical density is the ability of a material to transmit light through it. It measures the speed of light passing through a substance and is affected by the wavelength of light. At the same time, absorption is the transfer of wave energy when the wave passes through a medium. Absorption of light occurs in a denser medium. WebOptical density is a mathematical way of describing the extent of attenuation of visual lightwaves. Density is the log of opacity. Opacity is the reciprocal of transmittance. So a …
