Why is the objective lens of a refracting telescope bigger than the objective lens of a microscope?
The objective lens of a refracting telescope is larger than that of a microscope to gather more light and provide a brighter, clearer image of distant celestial objects. Telescopes are designed to view objects far away, requiring a larger aperture to increase light collection and resolution. In contrast, microscopes are used for observing small, close objects, where higher magnification is achieved with smaller lenses, allowing for detailed examination without needing the same light-gathering capacity.

Is refracting telescopes bigger then reflecting telescopes?
Not necessarily. Refracting telescopes can be large, but reflecting telescopes can also be quite large and often have larger apertures due to their design. The size of a telescope depends on its purpose and design specifications rather than whether it is refracting or reflecting.
What did Galileo's first telescope look like?
The shape of the lens means light near the top of the lens is bent down and light near the bottom of the lens is bent up. Somewhere inside the tube the light beams cross, but before they can spread out again the eyepiece lens bends the light beams again and sends them to the eye.
Which is bigger a reflecting or refracting telescope?
Reflecting telescopes tend to be larger than refracting telescopes because they do not suffer from chromatic aberration, allowing for larger apertures and therefore more light-gathering capability. This makes reflecting telescopes popular for professional observatories and research purposes. Refracting telescopes, on the other hand, are limited in size due to the weight and cost constraints of large glass lenses.
What telescope lens is more powerful?
A bigger one.
What is the difference between binoculars and microscope and telescope?
Ha! This is a subtle matter. Both magnify. A microscope magnifies something close to you, while a telescope magnifies something far away. But let's look deeper. Both telescope and microscope have an objective lens that projects an image called a real image. The eyepiece is used to further magnify a portion of the real image. The objective lens of a microscope is designed to produce a real image of something that is close to the lens, and the real image will be larger than the object you are looking at. Suppose it makes an image 10x larger. Then the eyepiece adds magnification. An eyepiece that by itself can magnify something 15x, when used to look at the image from a 10x objective, produces a total magnification of 150x. The objective lens of a telescope is designed to produce a real image of something that is at a much larger distance, and the real image will usually be smaller than the object (usually much, much smaller!). The longer the focal length of the objective, the larger the real image will be. Then it is the ratio between the focal length of the objective and the focal length of the eyepiece that determines the visual magnification. For example, may amateur telescopes use an objective lens or mirror (or some combination) that has a focal length of one meter, or 1000 mm (~40 inches). A common eyepiece focal length is 20 mm (~0.8 inch). 1000/20 = 50x. Large professional telescopes are typically never used for visual observing, but on rare occasions the 200 inch (5 m) Palomar telescope was used visually in the past. Its 55 foot focal length (16.75 m) when used with a 20 mm eyepiece would produce nearly 840x magnification. Both telescopes and microscopes can be used for photography by either putting the film or digital imaging sensor where the real image is in focus on it, or by using a special eyepiece to project an enlarged real image further back, where it might be more convenient to place the camera back with its lens removed.
How many times bigger does the image appear in a refracting telescope?
The image in a refracting telescope appears bigger by the magnification factor provided by the telescope's eyepiece. This is typically around 50-100 times for most amateur telescopes.
What is the difference between microscope and telescope and binoculars?
binoculars u carry around and can see things bigger telescope see things further microscope see things bigger
Which telescope is bigger refracting or reflecting?
"To build a large refracting telescope would require very strong supports to hold large enough lenses. These supports would tend to block out important light. So the refracting telescope is limited in its use. Today most large telescopes are reflecting telescopes." ~ BYU Home Study Astronomy course
What do we call an instrument that makes things look bigger?
Microscope, telescope.
What part of the microscope makes the object bigger?
objective lense

Why arent refracting telescopes bigger than reflecting telescopes?
If you are comparing the biggest telescopes in each type, that's because a large refracting telescope needs a huge lens, which gets expensive; also, the lens can't be supported, while a mirror can.
How many subsystems are in the universe?
Latest data indicates about a thousand, however the bigger the telescope, the better the microscope. Stick around.

What is the difference in refracting and reflecting telescopes?
A refracting telescope uses a series of lenses to magnify the light - like a simple spyglass, or a pair of binoculars. A reflecting telescope uses a concave mirror to gather light, which comes to focus at a point somewhere out in front of the mirror. It is then reflected sideways by another mirror into an eyepiece, which magnifies it. A refractor gives a bigger, but dimmer view of the distant object. A reflector gives a smaller, but brighter view of it.
What instrument makes objects look brighter and bigger?
A microscope uses lenses to magnify and illuminate objects to make them appear brighter and larger. By bending and focusing light, microscopes can reveal details that are not visible to the naked eye.
