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.

If the primary mirror of a telescope have a focal length of 225 centimeters and the eyepiece has a focal length of 7.5 millimeters then what is the magnifying power of the telescope?

The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X


What are the 4 properties of a telescope?

The four main properties of a telescope are its aperture (diameter of the primary lens or mirror), magnification (how much larger the telescope makes distant objects appear), focal length (distance from the lens or mirror to the focal point), and resolution (the ability to distinguish fine details or separate closely spaced objects).


Which power of a telescope is the least important?

The least important power of a telescope is likely the magnification power. While magnification allows you to zoom in on objects, other factors such as aperture size, optical quality, and clarity are more crucial for obtaining clear and detailed images.


What are three other objects used for magnification?

You can use : a microscope a telescope or a magnifying glass


What makes a telescope more powerful?

Several factors contribute to the power of a telescope. The size of the objective or primary mirror is a crucial factor, as a larger diameter allows the telescope to capture more light. The quality of the optics and the level of precision in their construction also affect the power of a telescope. Additionally, the type and quality of the eyepiece used can further enhance the power by magnifying the image.

What is magnifying power of a magnifying glass of power 12 dioptre?

The magnifying power of a magnifying glass can be calculated using the formula magnifying power = 1 + (D/4), where D is the power of the lens. In this case, with a power of 12 diopters, the magnifying power would be 4x.

How can the magnifying power of a simple microscope be increased?

The magnifying power of a simple microscope can be increased by using a lens with a shorter focal length, increasing the distance between the lens and the object being viewed, and adjusting the eye position to be closer to the lens. Additionally, using a lens with a higher refractive index can also help increase magnification.
