# Angular magnification of a microscope

• viperassasin
In summary, angular magnification is a measure of the magnifying power of a microscope, calculated by comparing the angle subtended by an object when viewed through the microscope to the angle subtended when viewed with the naked eye. The eyepiece of a microscope is responsible for providing the angular magnification by magnifying the image formed by the objective lens. The angular magnification can be changed on a microscope by adjusting the eyepiece or switching to a different objective lens. While angular magnification does not directly affect the resolution of a microscope, a higher magnification can result in a clearer and more detailed image.

## Homework Statement

The image formed by a microscope objective with a focal length of 5.00\;{\rm mm} is 160\;{\rm mm} from its second focal point. The eyepiece has a focal length of 26.0\;{\rm mm}. What is the angular magnification of the microscope?

## The Attempt at a Solution

don't know what equation I should use.

Look at magnification on wikipedia

no help

that doesn't help

## 1. What is the definition of angular magnification?

Angular magnification is the ratio of the angle subtended by an object at the eye when viewed through a microscope to the angle subtended by the same object when viewed with the naked eye.

## 2. How is angular magnification calculated?

Angular magnification is calculated by dividing the apparent size of an object when viewed through a microscope by its actual size.

## 3. What is the relationship between angular magnification and the eyepiece of a microscope?

The eyepiece of a microscope is responsible for providing the angular magnification. It magnifies the image formed by the objective lens and allows for a larger angle to be subtended at the eye.

## 4. Can angular magnification be changed on a microscope?

Yes, the angular magnification on a microscope can be changed by adjusting the eyepiece or by switching to a different objective lens with a different magnification power.

## 5. How does angular magnification affect the resolution of a microscope?

Angular magnification does not directly affect the resolution of a microscope. However, a higher magnification can provide a clearer and more detailed image, allowing for better visualization of smaller objects.
