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.
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 happens if you decrease a telescopes 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.)
How is magnifying power of telescope and a microscope are a affected by increasing the focal length of their objectives?
Increasing the focal length of the objective of a telescope will increase its magnifying power, allowing for higher magnification of distant objects. On the other hand, increasing the focal length of the objective of a microscope will decrease its magnifying power, as it will result in a wider field of view and lower magnification of small objects.
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.
Why camera shake more apparent when using longer focal length lenses?
Camera shake is more apparent when using longer focal length lenses because they magnify any movement made by the camera. This magnification effect makes even slight movements more noticeable in the final image. Additionally, longer focal length lenses have narrower fields of view, which can amplify the impact of camera shake on the composition.
How does the eyepiece affect the total magnifacation in a telescope?
A telescope consists of two lenses. 1) The main lens which collects the light ( it is relatively bigger that eyepiece). 2) Eye piece , through which we see. Magnification of a telescope depends on the focal length of the eye piece and the main lens. Magnification = Focal length of the main lens / Focal length of the eyepiece . For example : If the focal length of the main lens is 12 units and the focal length of the eyepiece is 2 units , then the magnification will be 12/2 = 6.When the focal length of the main lens is constant , the focal length of the eyepiece is inversely proportional to the magnification.
If a telescope with an objective lens of ten feet focal length is used with an eye piece of one quarter inch focal length what would the resulting magnification be?
To calculate the magnification of a telescope, divide the focal length of the objective lens by the focal length of the eyepiece. In this case, the magnification would be 480x (10 feet / 0.0208 feet).
What is the focal length of lenses?
The focal length of a lens is the distance between the lens and the image sensor when an object is in focus. It determines the field of view and magnification of the lens. A shorter focal length results in a wider field of view, while a longer focal length provides more magnification.
If a telescope has an objective with a focal length of 50 centimeters and an eyepiece with a focal length of 25 millimeter what will be the magnification?

How are images produced by the convex lens of a magnifying glass are affected by focal length?
The focal length of a convex lens determines the magnification of the image produced by the magnifying glass. A shorter focal length will result in a larger magnification, making the image appear bigger. Conversely, a longer focal length will result in a smaller magnification, making the image appear smaller.
