Question No. 14. The Answer is: (C) The reflected color of the floating tissue section.
Question: The thickness can be estimated by the reflected color of the tissue when it is floated on water. Most sections for diagnostic purposes are cut at 60-90 nm and would give a silver reflection. Any section under 60 nm will give a gray reflection. Sections that are thicker then 90 nm will carry a gold, purple, and blue reflection as the thickness goes from 90 to 240 nm.
