How many lenses do binoculars have?
It depends on the type of reflecting telescope.
Which type of telescope did Galileo turn skyward in 1610?
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.
The earliest telescopes which were constructed of two lenses in a long hollow tube are called?
Telescopes were first used in 1952 by Oxford scientist Ron L. Hubbard--his predecessor, Mallory Hieney, first saw the planets with his device. Its called a fefracting telescope.
What are some similarities and differences between refracting and reflecting telescopes?
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
Did Galileo design refracting telescopes?
Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person to use a telescope. That person would be Hans Lippershey. Hans Lippershey was born 1570 in Germany, but was raised in Holland. He invented the first refracting telescope in 1608. A lens maker, he designed this telescope from two lenses and applied for a patent, intending that it would be important for the military. He successfully demonstrated the usefulness of his refracting telescope to the military.
Where is the focus of a refracting telescope?
The focus is between the two lenses, closer to the eyepiece
How many convex lenses does a refracting telescope have?
At least two, but may have many. Depends on the design of the telescope.
What type of telescope uses two lenses?
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
How far apart are the two lenses of a refracting telescope?
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.

What uses two lenses and two mirrors?
On eyeglasses? Two lenses = bifocals Three lenses = Trofocals

How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.

Does a telescope use a convex lens?
Yes, a telescope typically uses convex lenses to gather and focus light. The objective lens, which is usually convex, collects and refracts light to create an image that can be magnified by the eyepiece lens.
