Certainly! Here are definitions for each of the terms:
### Incident Light
Incident light refers to any light that strikes a surface or medium. In optical physics, it represents the incoming light rays before they interact with a material. The properties of the incident light, such as intensity, wavelength, and angle of incidence, can significantly influence how much of it is reflected, transmitted, or absorbed by the material.
### Transmitted Light
Transmitted light is the portion of the incident light that passes through a material without being absorbed or reflected. It is the light that emerges on the other side of the medium after interaction. The amount of transmitted light depends on the properties of the material, including its thickness, transparency, and absorption characteristics, as well as the wavelength of the light.
### Absorbance
Absorbance is a measure of the amount of light that is absorbed by a material when light passes through it. It is defined mathematically as:
\[
\text{Absorbance} (A) = -\log_{10}\left(\frac{I}{I_0}\right)
\]
where \( I_0 \) is the intensity of the incident light and \( I \) is the intensity of the transmitted light. Absorbance is a dimensionless quantity and is used in various fields, including chemistry and biology, to quantify how much light is absorbed by a substance, which can be related to the concentration of that substance.
These definitions are fundamental to understanding various phenomena in optics, spectroscopy, and material science.
