How does a light microscope magnify an object?
A light microscope works on the principle of magnifying an object using visible light. The magnification is achieved due to the presence of two convex lenses, namely the objective lens and the eyepiece lens. When the object is placed on the stage, the objective lens collects and focuses the light passing through it. This creates a real image of the object inside the microscope.
The real image formed is then magnified by the eyepiece lens, which acts as a simple magnifying glass. The magnification of the object is calculated by multiplying the magnification of the objective lens by that of the eyepiece lens. The resulting magnified image can be viewed through the eyepiece.
The magnification of a light microscope usually ranges from 40x to 1000x, depending on the type of lenses used. The lenses of a microscope need to be properly aligned and maintained to avoid any distortion in the image.
In addition, the presence of illumination is necessary for the microscope to function properly. Illumination can either be provided by a built-in light source, or by an external light source, such as a beam of sunlight or a lamp. The light source should be bright enough to provide ample light for viewing the object, but not so bright as to damage the object being viewed.
In conclusion, a light microscope magnifies an object by using two convex lenses, working together to create a real image that is then magnified and viewed through the eyepiece. Proper maintenance and alignment of the lenses, as well as adequate illumination, are crucial for obtaining clear and accurate images.
