Difference between ocular and objective lens?
The ocular lens is located at the eyepiece of a microscope and is used to magnify the image produced by the objective lens. The objective lens is located close to the specimen being observed and is responsible for gathering light and forming the initial image.
What lens is used in a gun sight?

In microbiology what is the most commonly used ocular?
In microbiology, the most commonly used ocular is the 10x magnification ocular. This ocular is typically paired with a 40x objective lens to provide a total magnification of 400x, which is commonly used for observing bacterial and fungal structures.
How do you use the word ocular in a sentence?
This means related to the eye or eyesight. Here are some sentences.The ocular chart is easy to read.The doctor told me to do ocular exercises to strengthen my eyes.My ocular muscles are tired.
Where in the retina is the light focused nearsighted?
The retina is a light sensitive layer located at the back of the eye and is used by near and far sighted people.The lens of the eye controls how images are projected onto the retina and this is what causes sight problems such as near and far sight.
What is typical magnification of the ocular lens on a light microscope?
The typical magnification of the ocular lens on a light microscope is usually 10x, although some microscopes may have ocular lenses with magnifications of 5x, 15x, or even higher. This magnification works in conjunction with the objective lenses to provide a total magnification that can range from 40x to over 1000x, depending on the combination of lenses used.
What is the total magnification of a microscope with a 10X ocular lens and a 45X objective lens?
The total magnification is calculated by multiplying the magnification of the ocular lens by the magnification of the objective lens. In this case, the total magnification would be 10X (ocular) * 45X (objective) = 450X.
WHere are two lenses locate do in a compound microscope used in most classrooms today?
In most classrooms today, a compound microscope typically has two lenses located within the eyepiece and the objective. The eyepiece lens (or ocular lens) is located at the top of the microscope and is used to view the magnified image of the specimen. The objective lens is located near the specimen and is responsible for magnifying the image of the specimen before it reaches the eyepiece.
If a microscope has an ocular with a 5x power and has objectives with powers of 10x and 50x what is the total magnification of?
To calculate the total magnification of a microscope, you multiply the power of the ocular lens by the power of the objective lens being used. For the 10x objective, the total magnification would be 5x (ocular) × 10x (objective) = 50x. For the 50x objective, the total magnification would be 5x × 50x = 250x. Therefore, the total magnification can be either 50x or 250x, depending on the objective lens in use.
What did patricia bath invent?
patrica bath invented- a sugrical device used to remove cataracous lens and restore sight
What is a convex and a concave lens?
CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.
