How can the magnifying power of a telescope be increased?
a telescope's magnification is calculated as the ratio of the focal length of the primary objective to the focal length of the eyepiece. Since a telescope is defined by the primary objective, this part of it is essentially unchangeable. Therefore, the way to increase magnification is to decrease the focal length of the eyepiece. For example, a 1000mm objective and a 25mm eyepiece yields a magnification of (1000/25) 40x. Changing the eyepiece to a 10mm eyepiece increases magnification to (1000/10) 100x.
What would be the effect on magnification to increase the focal length of microscope and telescope?
The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.
What would be the magnification of a telescope with a focal length of 3000 millimeters using an eyepiece of focal length equal to 15 mm?
The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece. In this case, the magnification would be 3000 mm (telescope focal length) divided by 15 mm (eyepiece focal length), which equals a magnification of 200x.
Show How to calculate the magnification of a telescope with a 1000mm focal length an8-inch primary mirror a 4-foot body tube and a 25 mm eyepiece?
The apparent magnification of telescope optics is(focal length of the objective) / (focal length of the eyepiece)= (1,000 / 25) = 40 .The diameter of the primary mirror has no effect on the apparent magnification.The length of the body tube is involved in the case of the Newtonian configuration,only because it has to be long enough to hold the eyepiece in the right place.

What does the degree of magnification of a telescope?
The magnification indicates how much bigger something will be seen. For example, with the naked eye, the Moon has an angular diameter of half a degree; with a 40x magnification, it will look like it has 20 degrees.
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.
What is the formula for calculating the angular magnification of a telescope?
The formula for calculating the angular magnification of a telescope is: Magnification focal length of the objective lens / focal length of the eyepiece.

What is the relationship between magnification and the diameter of the field of view?
Magnification is inversely proportional to the diameter of the field of view.

The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece. In this case, the magnification would be 3000 mm (telescope focal length) divided by 15 mm (eyepiece focal length), which equals a magnification of 200x.
Is 100 plus magnification good?
Good for what? Telescope? Microscope? "Magnification" is often used as a marketing tool; telescopes for example might come with a maximum magnification that is too big to get a clear image, just so they can claim "100x magnification" or whatever. And it is cheap to get a magnification that is clearly too much. The most important piece of information about a telescope is, how big is the main lens, or the main mirror. A larger diameter here will give you (a) more light-gathering power, allowing you to see fainter stars, and (b) more resolution, roughly equivalent to usefulmagnification.Good for what? Telescope?

Refers to a telescope's ability to make an object larger?
Magnification refers to a telescope's ability to make an object appear larger when viewed through the telescope. It is the degree to which the image of the object is enlarged compared to what is seen with the naked eye.
