A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
a compound light microscope
A microscope is the instrument that uses light and two or more lenses to view cells. The lenses in a microscope help to magnify and focus the light on the sample, allowing us to see the fine details of the cell structure.
A compound light microscope allows light to pass through the specimen and uses two lenses (objective and eyepiece) to form an image. This type of microscope is commonly used in laboratories and educational settings for viewing cells, tissues, and other small specimens in detail.
A compound microscope is made up of two or more lenses. These lenses work together to magnify and focus light onto a specimen, allowing for detailed observation of small objects.
The type of microscope made up of two mirrors is called a reflecting microscope. It uses mirrors to reflect light and magnify the specimen being observed, rather than using lenses like a traditional compound microscope. This design is commonly used in high-powered microscopes for specialized applications.
On eyeglasses? Two lenses = bifocals Three lenses = Trofocals
It depends on the type of reflecting telescope.
Galileo turned a refracting telescope, which uses lenses to gather and focus light, skyward in 1610. This allowed him to make groundbreaking astronomical observations such as the moons of Jupiter and the phases of Venus.
Both concave and convex lenses are used in glasses; A microscope, like a reflecting telescope, uses a concave mirror, a plane mirror, and a convex lens; A refracting telescope uses two convex lenses to magnify images in the sky; binoculars use concave lenses to improve detail.
At least two, but may have many. Depends on the design of the telescope.
The focus is between the two lenses, closer to the eyepiece
The first telescope was invented by Hans Lipperhey , a Dutch lens grinder, in 1609 when he combined two lenses.

The distance between the two lenses of a refracting telescope depends on its design and purpose. Typically, the lenses are separated by a distance equal to the sum of their focal lengths. This separation allows the lenses to work together to focus light and form an image.
The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.
