What else can I help you with?
A microscope with only one lens is call what?
A simple microscope an electron microscope is one that uses the focus of electron beams instead of regular light from lenses. It allowed scientists to discover new germ cells, bacteria, and eventually viruses. the simple microscope was invented in 1600s
What is the white circular area that you see in the microscope?
it some thing on the lens im sure what its called but it marks the middle =)
Why did Zacharias Janssen invent the microscope?
The simplest answer is that they were created to see things, or details, that are too small for the human eye to see. Early tradesmen used simple lenses to see the intricate lines of engravings, or the clasps and fittings on jewelry. When eyeglass makers began combining pairs of carefully-ground lenses, they discovered the principle of optical magnification that is the basis for the microscope (and the telescope). In the case of the microscope, there were immediate practical applications in biology, anatomy, and miniature mechanical gearing.
When did Zacharias Janssen invent the compound microscope?
Hans Janssen and his son Zacharias Janssen, Dutch spectacle-makers, are frequently cited as having invented the first compound microscope in 1590, but there is a good deal of dispute. They may not have. Zacharias Janssen was the one who actually made the claim, and in the middle of the 1600's. A number of historians, however, agree that it is imporbable that 1590 is correct. There is a good deal of evidence that Zacharias Janssen was born somewhere around 1590. A link is provided to the Wikipedia article on the optical microscope where a brief history of the device can be reviewed.
Why is it that in a pair of bifocal glasses the converging lens at the bottom and the diverging lens at the top?
It is a split screen usually the bottom part is cut as the (close up) lens the normal or larger part of the lens is normal- depending on whether one needs primarily distance or close-up correction, or for reading. the bottom lens group is usually secondary, not the main task. Franklin invented bifocal eyeglasses. He also devised the lightning rod, Franklin stove and *Long arm, lever device often used in grocery stores.
How does the lens of a light microscope worke?
Each concave lens bends light to make the object appear larger
How does the lens of a light microscope work a. Each concave lens bends light to make the object appear larger. b. Each convex lens bends light to make the object appear larger. c. Each convex lens be?
b. Each convex lens bends light to make the object appear larger. The convex lens in a light microscope refracts and converges light rays to magnify the specimen being observed. By bending light, the lens creates an enlarged virtual image of the specimen that can be viewed by the observer.
What are three things that have been used in a microscope?
Lens, light, mirror
Is magnification the ability to make things larger than what they are?
magnification is the ability to make things larger they they actually are by taking the lens from a microscope or by just using a microscope and magnifying the object.
Why does a microscope use a convex lens?
A convex lens is used in a microscope to magnify the image of the specimen being examined. The shape of the lens allows it to focus light rays and produce a larger, clearer image for observation.
What is lens of light microscope?
optical microscope
Does a microscope make small things larger or larger things smaller?
A microscope makes small things appear larger by magnifying them. It does not change the size of the actual object, but only enlarges the image that you see through the lens.
Which object is used to focus light in a light microscope?
The lens is the object used to focus light in a light microscope. The lens in a light microscope is typically found within the objective lens or the eyepiece, and it helps to magnify the image of the specimen.
What structures of an electron microscope are comparable for the light microscope?
In an electron microscope, the condenser lens is comparable to the condenser lens in a light microscope, as both concentrate and direct the light/electron beam onto the specimen. The objective lens in an electron microscope is similar to the objective lens in a light microscope, as both magnify the specimen image. Additionally, both types of microscopes have a stage where the specimen is placed for observation.
What is An advantage of a compound light microscope over a single lens microscope?
A compound light microscope is able to provide more clarity and detail than a single lens microscope, which is its advantage. Compound refers to the microscope having more than one lens.
What object is used to light in a light microscope?
Lens
Does a compound microscope have one lens?
A compound microscope has two lenses: the objective lens and the eyepiece lens. The objective lens is used to gather light from the specimen and create a magnified image, which is further magnified by the eyepiece lens for viewing.
