What are two problems with refracting telescopes?
Images are not always clear because the light is being bent.The size of the lens is limited which limits the power of the telescope.
What is the difference between tacky glue and regular glue?
Tacky glue has more adhesive power and it dries flexibly, unlike regular glue which can dry hard and flake off.
Which of these statements accurately describes a difference between English politics under the Magna Carta and those established just after William the Conqueror's invasion of England?
The Magna Carta limited the power of absolute monarchy, while William the Conqueror's invasion had expanded it.
What is the difference between parallel and series?
If you are referring to an electrical circuit, a series circuit is wired in such a way that if one object is removed from the circuit, the circuit is broken and everything within the circuit loses power. In a parallel circuit different components of the circuit can be removed without disabling power to the rest of the devices within the circuit.
What is the difference between a car sputtering and a car missin?
Sputtering is almost like a person spitting. The car runs but it doesn't have full power, could actually sound like someone spitting. Missing is when there is a consistent and constant slight jerking or vibration. Unless it is really bad it is hard to feel.
How is the size of a reflecting telescope indicated?
The size of a reflecting telescope is typically indicated by its aperture, which is the diameter of the primary mirror. Aperture size plays a crucial role in determining the light-gathering ability and resolving power of the telescope.
What are some of the advantages of reflecting telescopes over refracting telescopes?
Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
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.
What is the difference between a reflecting telescope a refracting telescope and a radio telescope?
Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera. Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is. Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope. The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.
Who was an English scientist and mathematician who invented the telescope which used mirrors instead of lenses?
Isaac Newton was credited for building the reflecting telescope in 1668. The reflecting telescope design is now very widely used by amateur and professional astronomers, because the cost per square inch of aperture (diameter, the light gathering power) is less than the other designs.
What is the magnification of a reflecting telescope with an eyepiece of focal length 25 mm and an objective lens of focal length 2000 mm?
That's 80 power.
A telescope that suffers from chromatic aberration and has a low light gathering power is most likely?
a cheap refracting telescope with a simple lens system. Chromatic aberration occurs when different colors of light focus at different points, and low light-gathering power could be due to a smaller aperture size.
How did newton's invention of the reflecting telescope affect the field of astronomy?
Newton's invention of the reflecting telescope improved the quality and resolving power of telescopes, allowing astronomers to see fainter and more distant celestial objects with greater clarity. This advancement revolutionized observational astronomy and laid the foundation for future telescope designs.
Reflecting telescopes are popular because they're a more powerful than a refraction telescope b smaller than a refracting telescope c easier to build than a refraction telescope d more durable?
They can pack a lot of light gathering power into a more compact body. And Maksutov-Cassegrain Telescope does much better.
What is used in a telescope to reflect light?
Reflecting telescopes use mirrors to collect light.
What do you mean by resolving power of telescope?
The "resolving power" of a telescope is a measure of the ability of a telescope to distinguish between two separate objects that appear to be very close together in the sky.
