Answer 1

Answer:

Absorbance will come in blank

Answer 2

The optical denseness of a medium is measured in terms of the Refractive index

Detailed answer

A spectrometer is used to measure the optical density of a medium.

• Refractive index is  "the measure of the bending of a ray of light when it passes from one medium to another"
• Optical density is defined as the total amount of attenuation or intensity that is lost when light passes through a denser to a rarer medium.
• The optical density of a medium depends upon the velocity of the light in that medium.
• It can be determined at any wavelength
