(a) Interpretation: Whether a tiny ant can be seen by optical microscope but not by human eye or not should be determined. Concept introduction: Objects are categorized on the basis of size range they fall in. Macroscopic objects are those which lie in the size range that human eye can perceive and microscopic objects are those which need the use of specialized instruments like electron microscope or atomic force microscope. Human eye can detect approximately up to the size of 10 μm and optical microscope can detect in the size range of 1 mm − 1 μm . Detection size limit for (EM) electron microscope and (AFM) atomic force microscope is 100 μm − 100 pm and 5 μm − 100 pm , respectively.
