Answer:
see below
Explanation:
refractive index of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in medium
critical angle of glass is 42 means that if the angle of incidence inside the glass is 42 degrees, then the angle of refraction in the optically less dense medium will be 90 degrees

<h3><u>Answer;</u></h3>
<em>too small to be seen with an optical microscope </em>
<h3><u>Explanation;</u></h3>
- <em><u>An electron microscope is a type of microscope that is used to observe very tiny specimens whose features can not be observed by other types of microscopes.</u></em> It uses a beam of electrons to generate an image of a given specimen whose features can be clearly observed and studied.
- <em><u>Electron microscope has very high resolution and magnification as compared to other optical microscope </u></em>hence can be observed in the study of micro-organisms such as viruses which would be difficult to study their features using optical microscopes.
