At normal adjustment, the distance between the two lenses is equal to the sum of the focal lengths of each lens.

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 length is the hubble telescope?
The length is 43.5 feet (13.2 m).
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 is length of galilean telescope?
Galileo's telescope was about 92.7 centimeters long. 36.5 inches long.
What is the function of the fine and coarse adjustments?
With the "coarse" adjustment, the adjustment mechanism causes a large amount of movement in the thing being adjusted with very little movement of the adjusting mechanism. With the "fine" adjustment, the adjustment mechanism causes a small amount of movement in the thing being adjusted with a lot of movement of the adjusting mechanism. Frequently the two adjustments will be two knobs each with different gearing - say on a telescope focus mechanism. The coarse adjustment allows the telescope focus to be moved quickly then the fine adjustment allows the observer to gently bring the focus to be "pin sharp".

What is the elevation adjustment on a telescope?
Up n' down.
What is the ideal focal length for a satellite dish?
Infinity. Space is so far away from the dish that using a focal length of infinity is standard. Any focus adjustment is merely to account for changes in temperature of the dish (or telescope).
What is a coarse adjustment knob?
The part of a telescope were you adjust the size of the lens
Why don't i get a clear image with my telescope?
There are several possible reasons: * Your telescope may be of a low quality. * It may need some adjustment. * You may have expectations that are simply too high for your telescope type.

What is the power of the eyepiece?
The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.
Most powerful telescope in the world?
it should be the hubble space telescope because it can see 10 times better than a normal telescope

Why do we need a telescope?
A telescope enables the user to see far more into the distance than with normal eyesight.
