Why does the author mention “a telescope” as part of the discussion of microscopes? A. To show how microscopes and telescopes are different B. To emphasize the importance of magnification in all optical devices C. To explain how the development of the microscope depended on the invention of...
Why are modern light microscopes better than the ones leeuwenhoek used? What are the advantages and disadvantages of radio telescopes? Why did Justus von Liebig invent the mirror? Why is it necessary to adjust the amount of light after changing objective lenses? Why does chromatic aberration occur...
Why is the maximum resolution and magnification of a light microscope less than the electron microscope? Explain why the resolution achieved by electron microscopes are so much greater than those achieved by light microscopes. Despite the relatively low magnification capabilities of a light mi...
1670s: Antonie van Leeuwenhoek, a Dutch scientist, begins his work developing better microscopes that allow scientists to see cells and the organelles they contain more clearly. 1839: German scientists Matthias Schleiden and Theodor Schwann describe the first two parts of the cell theory.Schleiden st...
When a light beam passes from an optically denser medium to an optically less dense medium(and vice versa),the direction and the speed of light changes. My question is why light must bend when it goes from one medium to another. Say,it goes from air to water. Water is optically denser...
Petrographic observations (with the help of polarizing microscopes) have also been used in paleoanthropology and archaeology to describe and constrain quartz-rich rock characteristics. However, studies on the raw materials at the Olduvai sites usually failed to recognize and/or misinterpret diagnostic roc...
Microscopy and macro are more esoteric and harder to do for some, and they often expose imagery that can be strange or "icky" to the uninitiated. It has its own beauty, but it can be an acquired taste. Microscopes also have the
Although they didn’t have proof at the time didn’t mean they were wrong, eventually what they felt was confirmed by tests and microscopes. No physical evidence doesn’t mean no possibility of the idea or situation. The thoughts and ideas of the doctors or scientists was proof of what was...
to the microscopes you fuckers would win we're just saying that you're fast you get there first you lapped home would be flapping in the wind I get there like three minutes later all cramped up with you are you looking at bacteria no you go fresh here's gopher please much does a Bul...
Why do animals' eyes reflect light? Why are there no blue cones in the fovea? Why does light refract in a prism? Why are concave mirrors used in telescopes? Why are there no rods in the fovea? Why are modern light microscopes better than the ones leeuwenhoek used? ...
