Microscopes

No.They are not but they are good for observing cells.

These are both high resolution microscopes that both use electron beams.

The size of DNA is way too small to be seen by a microscope. X-ray Crystallography can be used because it sends x-rays at a molecule and then the machine measures the pattern of the x-rays to construct a 3D image of the DNA molecule

primary lenses are that lenses which are maked by leunhoek .these lenses are used to see parts of different objects and these lenses had maked first.they are mostly used in ancient time.

In 1850, John Lawrence Smith invented the inverted microscope. He was a faculty member at what is now Tulane University.

In a simple microscope, a lens magnifies the image of the sample.

in a compound microscope, the objective lens magnifies the image (there may be more than one objective lens) and the eyepiece lens enlarges the virtual image (which is typically inverted by the objective lens).

Liquids and gases expand inside a vacuum, so the organism's shape would be destroyed..

Robert Hooke did NOT invent the microscope. He only perfected it. He made the discovery of a cell.

they can see them up close and can identify the cells.

i am not sure of what kind of microscope you need, but not something cheap at all,

i can remember that i did this on a really cheap one a couple of years ago, a normal stereo microscope (optic) should work fine ;3

Generally viruses are smaller than bacteria, which are themselves smaller than animal and plant cells. Therefore D is the smallest and is least likely to be visible using an ordinary microscope.

See related links for an interactive scale of cells, from the macroscopic to the microscopic, down to a single carbon atom.

1. There are no bacteria on the slide.
2. Your lens cap is on.
3. You are not looking in the right place.
4. The microscope is in the wrong focus.

There are special microscope slides available, which have on them a millimeter scale graduated down to 1/100 of a mm. Manufacturers of microscopes make these.

field of view

are thin slides of rock or mineral mounted to a microscope slide.

I think Biology was the science that began because of the microscope

they used tiny pieces of glass that reflects light and make the images bigger and clearer

1.hold the neck with one hand 2. put your other hand underneath the base 3. Wind stage all the way up to the top 4. Make sure that the smallest objective lens is in front 5. place slide in the centure of stage and put the stageclips on 6. look throught the eyepiece and focus the slide 7. when you are finished take the slide off and get a piece of lens paper NOT A TISSUE OR TOILET PAPER THAT RUINS THE LENS 8. wipe each objective lens with the lens paper and the eyepiece to 9. DO NOT TOUCH THE LENS WITH YOUR FINGERS!!! THAT RUINS IT TO!! 10. place dust jacket over microscope and carry it (repeat steps 1&2) to a safe place. 11. Store it in a clean, dry place.

It's a humourous "Rap song" about the microscope - check it out on YOU TUBE http://jp.youtube.com/watch?v=hVxMPLrzv4A

The term microscope technically applies to any magnifying arrangement of lenses, one or many.

Single lens magnification has been known since about 1000 AD and no inventor is recorded by history.

Around 1590, several individuals compete for recognition as the inventor of the compound microscope which is a microscope using two or more lenses. See the link below to the related question, "Who invented the microscope?"

About 1670, Anton van Leeuwenhoek dramatically increased the magnifying power of the simple microscope.

Have you tried Numrich Gun Parts? I was able to get some parts for mine from them. Also, they are suggested by Marlin if you call them looking for parts. They have a website, just search Numrich. I can't think of the address right now. Hope that helps.

the hand lever is the part of microscope....

the microscope need to see the small things or viruses....

The lamp housing on a microscope houses the light source (typically a bulb or LED) that illuminates the specimen being viewed. It helps to provide sufficient and adjustable illumination to enhance the visibility of the specimen under observation.
