Multiple Choice

Resinous mounting media have an index of refraction much lower than that of the tissue.

Explanation:
The main idea is that mounting media are chosen to match the tissue’s optical properties to minimize light scattering and improve clarity. Resinous mounting media are formulated with refractive indices close to that of tissue (and glass), typically around 1.50 to 1.55. If the mounting medium had a much lower index than the tissue, large refractive mismatches would cause scattering and optical loss, reducing image quality. Therefore, resinous mounting media are not much lower in refractive index; they are similar to, or slightly higher than, tissue. That’s why the statement is false.
