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 will decreasing a telescope's eyepiece focal length?
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)
What is the focal length of a telescope's mirror if I use an eyepiece with a focal length of 26 mm and I get a magnification of 70x?
The focal length of the telescope's mirror can be calculated using the formula: Telescope focal length = Eyepiece focal length × Magnification = 26 mm × 70x = 1820 mm Therefore, the focal length of the telescope's mirror would be 1820 mm.
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.
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 parts of the body can be affected by focal dystonia?
Focal dystonias may affect the neck (cervical dystonia or torticollis), the face (one-sided or hemifacial spasm , contraction of the eyelid or blepharospasm , contraction of the mouth and jaw or oromandibular dystonia
What is Merge's syndrome?
Other types of dystonias include Merge's syndrome (spasms of the jaw muscles when opening and closing of the mouth).
The distance from lens to focal point is called?
The distance from a lens to the focal point is called the focal length.
What are the differences between primary and secondary dystonia?
Primary or idiopathic dystonia is presumed to be of genetic or unknown cause, whereas secondary dystonias are due to an attributable cause.
What is defined as the distance between a lens and its focal point?
focal length of the lens
How does the focal plane change as you change magnification?
It does not. For an explanation of "focal plane" see the question What is the focal plane?
Use the word length in a sentence?
Focal Point:The distance from the Lens to the Focal Point is called the Focal Point.
What is focal calcifications?

When was Focal Press created?
Focal Press was created in 1938.
When was Focal-JMLab created?
Focal-JMLab was created in 1979.
What is the population of Focal-JMLab?
The population of Focal-JMLab is 213.
What is the distance from the center of a mirror to a focal point called?
The distance from the center of a mirror to the focal point is called the focal length.
