if an opaque object is viewed through a compund light micro, what will you see? through a steromicroscope?

Question

please give me an ans. in an hour! i'll give 10 to the first complete answer.

Answer 1

Compound light microscope - nothing, because it needs to be transparent for light to pass through it and see detail. You will just see a silhouette.

Stereo microscope works by reflected light, from above the object, so you will see the object better.

Answer 2

Compound light microscopes are "Transmission Microscopes". That means they view the light coming *through* a transparent (or very thin) sample. These are the stereotypical microscopes that you use slides and coverslips for.
Steromicroscopes are "Reflection Microscopes". So they illuminate the object to be viewed from above, and visualise the light that is *reflected* from the surface of the object. They also use two independent lens systems (one for each eye), so they give you a 3D image.

So - you won't see *anything* for an opaque sample through a compound 'scope, but you will see the surface features, colour, etc. through a stereo microscope.

Answer 3

there is no true opaque material. Whenever light strikes a surface , some of it gets transmitted (passes) through the surface, some of it reflects and some of it absorbed. Transparency depends on the amount of light passing through the surface and similarly opaqueness depends on how much light is reflected back or absorbed. In addition to the material , it also depends on the frequency of the light you are using . If you talk about the visible range (which is referred to light) violet will penetrate more than red because of higher frequency and thus higher energy.
