How to Improve angular resolution of telescope?
To improve the angular resolution of a telescope, one can increase the diameter of the telescope's aperture, as larger apertures gather more light and reduce diffraction. Another method is to use adaptive optics, which corrects for atmospheric distortions in real-time. Additionally, employing interferometry, which combines signals from multiple telescopes, can enhance resolution by effectively increasing the aperture size. Lastly, observing at longer wavelengths can also help to achieve better resolution in certain conditions.
Why does the diameter of the telescope aperture matter?
The diameter of the telescope aperture determines how much light the telescope can gather, which impacts the brightness and detail of the images it can produce. A larger aperture means more light can be collected, allowing for clearer and sharper views of celestial objects.
Why does a larger telescope allow astronomers to see more?
A larger telescope has a greater light-collecting area, which allows it to gather more light from faint objects in space. This increased light-gathering ability improves the telescope's sensitivity and ability to detect fainter objects, providing astronomers with clearer and more detailed images. Additionally, a larger telescope can have higher resolution, allowing for sharper and more detailed observations of celestial objects.
How do astronomers use active optics to improve telescope resolution?
In past years, the light collecting power of telescope has been improved by building telescopes with of larger diameters with larger collecting areas, thus allowing for the detection of fainter and more distant objects
Was Galileo able to see the rings of Saturn through his telescope?
No, Galileo was not able to see the rings of Saturn through his telescope. The resolution of his telescope was not powerful enough to distinguish the rings, so he mistakenly described Saturn as having "ears" or handle-like appendages. It was only later astronomers with more advanced telescopes who were able to see and identify Saturn's rings.
What is better a 60mm or a 70mm telescope?
70 mm. The numbers refer to the diameter of the main lens or mirror; the larger this number, the more light-gathering the telescope is, and also, the higher its resolution will be.70 mm.

Which power will allow you to see more the object?
Increasing the resolution or magnification of the optical instrument, such as a microscope or telescope, will allow you to see more details of the object.

What is their major disadvantage of a telescope in space have over a telescope on Earth?
A major disadvantage? Size. It's expensive to launch a telescope into space, the heavier the object, the more expensive. You have to balance the size (thus weight) of a telescope against the cost, and the capability of the rocket. In astronomy the major factor in a telescopes effectiveness is size. The bigger the telescope, the dimmer the object that can be observed, which often means the more distant objects, and the higher resolution images they obtain. Space telescopes give this all up to be above the atmosphere because the air restricts the resolution of images, as it distorts the light that passes through it. So in exchange for better resolution (not limited by the atmosphere) they give up size. On top of this you have maintenance issues, as it's normally impossible to fix you have to have simpler, more robust (and expensive) instruments which can limit what you can do.
What makes a telescope powerful?
The light-gathering power of a telescope is determined by its aperture, which refers to the width of a telescopes primary mirror or objective lens.

Interferometry uses two or more telescopes to achieve?
a light-collecting area equivalent to that of a much larger telescope.an angular resolution equivalent to that of a much larger telescope.both the light-collecting area and angular resolution of a much larger telescope.Correct answer: an anguar resolution equivalent to that of a much larger telescope. ;-)
What is the difference between a reflecting telescope and a refracting telescope?
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
How does sensor resolution relate to its angular resolution?
Sensor resolution refers to the number of pixels in the sensor, while angular resolution relates to the ability of the sensor to distinguish between closely spaced objects. A higher sensor resolution can contribute to better angular resolution by providing more detailed and accurate image data for analysis and interpretation. However, factors such as optical quality and sensor size also play a role in determining angular resolution.

What is the significance of the Galilean telescope ray diagram in understanding the functioning of the Galilean telescope?
The Galilean telescope ray diagram helps us understand how light rays pass through the lenses of the telescope to produce an image. This diagram is important because it shows how the lenses in the telescope work together to magnify distant objects, allowing us to see them more clearly. By studying this diagram, we can better grasp the optical principles behind the Galilean telescope's functioning.
