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.)
What happens to focal length when convex lens is cut horizontally?
no change
How are the numbers related to the length of the objective?
Because the length of the objectives depends on the total magnification. Example: Magnification: 50x (LPO) You can see that the lower the magnification,the length of objective is the smallest. Magnification: 500x (HPO) You can see that the higher the magnification, the length of objective is bigger than the other objectives. If the objective is lower, the number is lesser -Guinean026
Will the focal length of concave lens change in water?
no, because this happens only in the cases of lenses
How do you calculate magnification?
Divide the focal length of the objective lens by the focal length of the eyepiece.
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.
Does the numerical aperture of an objective depend on the focal length of the objective?
Yes, the numerical aperture of an objective lens is influenced by both its focal length and the refractive index of the medium it is used in. A higher numerical aperture typically corresponds to a shorter focal length, allowing for greater resolution and light-gathering ability.
How do I calculate the f stop of a fixed power spotting scope using only the objective lens diameter and the magnification of the device?
To calculate the f-stop of a fixed power spotting scope, you can divide the diameter of the objective lens by the magnification of the device. The formula is f-stop = objective lens diameter / magnification. This will give you the f-stop value which represents the aperture opening of the spotting scope.
What happens If a muscle is applied to a load that exceeds the muscle's maximum tension?
The muscle length will not change during a contraction.
Which part are the ocular and objectives connected to?
The telescope tube is between the eyepiece and the objective lenses. It usually consists of two tubes one of which slides inside the other to change the length.
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.)
Which lens in a refracting telescope has a shorter focal length?
The objective lens in a refracting telescope typically has a shorter focal length compared to the eyepiece lens. This is because a shorter focal length allows for higher magnification and better light gathering capabilities.
