# How is ocular magnification calculated?

## How is ocular magnification calculated?

To calculate the magnification, simply multiply the ocular lens (10x) by the objective lens. With this microscope you can obtain four different magnifications: 40x, 100x, 400x and 1000x.

## What is the limit of resolution of the human eye?

A model of the perception limits of the human visual system was given, resulting in a maximum estimate of approximately 15 million variable-resolution pixels per eye.

## Can the human eye see the difference between 1080p and 4K?

In short, it depends. The difference between 1080p and 4K is undeniable in that a 4K screen is capable of displaying four times the number of pixels as a 1080p screen. From a distance, it is virtually impossible for someone to tell the difference in quality between a 1080p and 4K screen.

## What is the limit of resolution of naked eye?

The angular resolution of the naked eye is about 1′; however, some people have sharper vision than that.

## What is the smallest particle visible to the human eye?

To give you a better idea of just how small a micron is, consider this: the diameter of a human hair is 80 to 100 microns in size. If (A) is the diameter of a human hair (100 microns), then (B) is the size of the smallest particle visible to the human eye (50 microns), and (C) is the size of a 0.5 micron particle.

0.1mm

## What is a quark in simple terms?

: any of several elementary particles that are postulated to come in pairs (as in the up and down varieties) of similar mass with one member having a charge of +²/₃ and the other a charge of −¹/₃ and are held to make up hadrons.

## What happens when a particle and its antiparticle collide 2 points?

Annihilation, in physics, reaction in which a particle and its antiparticle collide and disappear, releasing energy.

## Do quarks actually exist?

Quarks do exist! However we are not able to seen them directly, since the strong energy force between them increases as we tried to separate them from each other. The Quark-gloun plasma is a hypothetically state of matter in which quarks and gluons are free to move.

## Do quarks decay?

Up and down quarks can decay into each other by emission of a W boson (this is the origin of beta decay due to the fact that the W can, depending on its type, decay into electrons, positrons and electron (anti-)neutrinos, ). The current understanding of quarks is, that they are a fundamental particle.
