My professor of Biomedical Optics course asked us to think upon the evolution of the reflection coefficient with the absorption coefficient $\mu_a$, the reduced scattering coefficient $\mu_s'$ and the refractive coefficient of medium $n_2$.
Here I share what are my thoughts:
For a highly absorbent medium, hence with high $\mu_a$ we will have less reflection since part of the incident light is absorbed in the medium itself
For a highly scattering medium, hence with $\mu_s'$, it will be highly probable that the incident light will be back-scattered. Thus the reflection coefficient will be higher
Changing the refractive index $n_2$ will change the angle of the refracted light but won't have any effect on the reflected light
I'm not very sure about my answers and I feel like thay are not correctly supported by a convincing explanation.
Can you help me provide better answers?
Thank you in advance!
