Magnification of a Microscope
The magnification of a microscope refers to the increase in the size of an object under observation. In the case of the chicken liver DNA, using a microscope allowed us to see the incredibly small structure of the DNA strands in greater detail.
There are two types of magnification in a microscope: objective magnification and eyepiece magnification. Objective magnification refers to the magnification produced by the objective lens, whereas eyepiece magnification refers to the magnification produced by the eyepiece or ocular lens.
Objective lenses come in different magnifications, most commonly 4x, 10x, 40x, and 100x. The magnification of an objective lens is indicated by a number followed by an “x”. For example, a 40x objective lens magnifies an object forty times its original size.
To determine the total magnification of a microscope, you need to multiply the magnification of the objective lens with the magnification of the eyepiece. For example, if the objective lens is 40x and the eyepiece is 10x, the total magnification would be 400x.
It’s essential to note that the resolution of a microscope also plays a vital role in the clarity of the image. Resolution refers to the ability of the microscope to distinguish between two points. It is influenced by the numerical aperture, wavelength of light, and quality of lenses used in the microscope.
In conclusion, magnification is an essential feature of a microscope that allows us to visualize and study small objects in greater detail. To achieve higher magnification, objective lenses with higher magnification are used, and eyepieces with greater magnification are employed.
