yes
Field of view will decrease as the aperture remain same but things become larger and so we can see smaller area after magnification
A calibrated focal length is an adjusted value of the equivalent focal length on a camera, so as to equalize the positive and negative values of distortion over a field.
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.)
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.
The focal length is the sicence that deals with when make this image on the screen about disruption or clear and we can use it in the field of elicrical technology and etc...
decreace ;)
it would increase

It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
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
More the curvature of the eye lens, lesser the focal length is. Lesser the curvature, greater the focal length is
The lens in a door peephole is a convex lens with a very short focal length, giving it a wide field of view. If it were on a camera, it would be called a "Fisheye lens".
