Why Is a Hand Lens Referred to As a Simple Microscope& the Light Microscope Called a Compound Micros

A simple microscope has only one lens and a compound microscope has more than one lens. A rudimentary compound microscope has two lenses: the Object lens (the lens closest to the object being viewed) and the Eyepiece (the lens closest to your eye). Many microscopes have two or more interchangeable Object lenses which give the user a choice of different magnifications.

1. Why should I use a light microscope?

A light microscope has a wide field of view, produces images of the interiors of objects (not just surfaces), displays multiple objects simultaneously, shows colors, is easy to maintain , and is relatively cheap. Many light microscopes are equipped for specialized work. For example, a polarized light microscope enables you to identify crystals, measure refractive index, determine strains, and more. A fluorescence microscope enables visualization of small biological details with high contrast. A metallographic microscope is used to look at microstructures of polished metals. With the appropriate instrument, a light microscope enables you to do a lot of work quickly. Why should I use a light microscope?.

2. Why is the light microscope also called the compound microscope?

The image path contains more than one lens. A magnifying glass is a "simple" microscope

3. can bacteria be seen using a light microscope?

Yes but only just - they are on the limit of resolution of the light mic. even using an oil immersion lens. John H

4. Which colour is used in a light microscope to get the best possible resolution?

Heh, as the electron microscopist who provided the equation for the Abbe limit would likely tell you, the answer is no.The highest resolution imaging techniques available do not use photons. They use "smaller" particles like electrons. There are however a few techniques for optical imaging that allow for the discernment of features smaller than the Abbe limit. Some of these use some form of computational photography to calculate what the sample must be like when multiple images of lower resolution are combined. STORM and 4Pi work this way.Another possibility is the use of FRET or similar fluorescence based techniques to infer additional information about position, not necessarily by creating a normal image. Fluorescent molecules can transfer their energy to other flourescent molecules without emitting a photon. Therefore, if you shine a light on a sample that should stimulate emission in one fluorophore but not the other, you will know the two fluorophores are close enough together for FRET to occur if you get emitted light of the second flurophore's wavelength.I am a developmental and evolutionary biologist and I suspect that a physicist or professional microscopist could explain this much better than I. However, super resolution microscopy and fluorescence are both VERY cool and worth reading up on even if it's not terribly related to your field of study. I am attaching a Wikipedia link on both:Super-resolution microscopy - WikipediaFluorescence - WikipediaWhich colour is used in a light microscope to get the best possible resolution?

5. which phase of the cell cycle could you identify most readily with a light microscope?

M Phase: karyokinesis and cytokinesis The various stages of interphase are not usually morphologically distinguishable.

6. help!! light microscope question!!?

Does it have a picture of a microscope? You should be able to follow the path of the light. It starts at the light source, then the specimen, then the objective lens, then the body tube, and finally the ocular lens.

7. How did the light microscope make the cell phone possible?

It's not quite that simple... The technology required by cell phones covers everything from microscopes through to membranes, electricity and magnetism, quantum mechanics and rockets. Miss out any of these, and we would never have a cell phone...

8. outline the role of a light microscope with the study of cells:thanks?

Compund light microscopes contain 2 or more objective lenses with different magnifications, and also one eyepiece lens. These magnifications can be adjusted to be able to view cells more clearly. Although, none of the cell organelles can be seen with light microscopes (that's what electron microscopes are for), a distinct outline of the plasma membrane should be seen, as well as the outline of the nucleus. This enables the viewer to determine the general shape and structure of a cell
