a glass disk that fits in a microscope eyepiece and that has a ruled scale; when calibrated with a slide micrometer, direct measurements of a microscopic object can be made.
they create the glass then heat it and then bend it and hold it there until it cools.
yes. these panels are made of glass and when glass is dropped it shatters. it might not shatter into a million pieces but any glass object can break
microscope is made up of thousands of small prisms....
A prism. It can be made of glass, crystal, or other hard clear material.
lens
Glass or plastic.

the magnifying glass has a convex lens and it curves to magnify objects.
To find the refractive index of a glass slab using a travelling microscope, you would first place the glass slab on a flat surface. Using the travelling microscope, measure the apparent shift in the position of the object when viewed through the glass slab. By knowing the thickness of the glass slab and the shift in the position, you can calculate the refractive index using the formula: Refractive index (n) = (apparent shift + 1) / actual shift.

They are MAGNIFIED ... as with a microscope or a magnifying glass.

they are made of glass because it is transparent and nonpermeable so no liquids can pass through it it is hard aswell so it will not break easily
A round piece of plate glass is heated and slumped over a curved steel form then silvered on the convex side. Better ones were made by grinding and polishing a convex surface to one side of flat window glass then silvered on the curved side.
