Question

what is optical density​

Answer 1

Answer:

Optical density is the process of transmission of light or other electromagnetic radiation by matter. The process of emission and absorption depends on the wavelength of the radiations, which includes the interaction between fundamental particles like electrons, atoms, ions, etc.

When a beam of light interacts with absorbing atoms, absorption takes place. It depends on the sample’s thickness and the concentration of the absorbing atoms.

Hope it helps.

Answer 2

Answer:

It is often said to be identical to the absorbance. It is a logarithmic ratio of the falling radiation to the transmitted radiation through a material.

For a given wavelength, the expression of optical element transmittance is expressed as:

Log10 (1/T)

Where T is transmittance
