Working Process of The Magnifying Glass
The magnifying glass is known as one of the most ancient optical devices. Thousands of years ago, Egyptians used obsidian or chips of crystal to enhance a small object. The famous English philosopher Roger Bacon designed the first magnifying glass for scientific purposes
during the thirteenth century.
Generally, magnifying glasses are made of double-convex lenses and they are used to make an object bigger. And this is done by placing the lens very close to the object so that it can be seen clearly. The light rays are bent towards the lens’ center. When these bent rays reach the eye, they make the object larger than its actual size.
If the object is far enough away from the lens, the image will flip, and it will appear smaller and upside down. The distance at which this flip occurs is twice the focal length of the lens. The focal length of any lens is determined by how many curves are present on the lens’s face. The magnified image is called a virtual image. And the inverted image, as well as the smaller one, is known as the real image.
How Magnifying Glass Works
An object is placed in the focus of a convex lens within a distance. When looking at the object from the other side of the lens, you can see a straight, unrealistic and magnified image of that object. Now the extended image will be closer to the eye, the widening angle of the eye will be larger and the image will look larger. But if the image is formed closer than the point near the eye, the image will no longer be seen clearly. It will give a blurry look. When an object's image is formed at a distance close to the eye, that is, the visible point, it is most apparent in the empty eye. And for objects that are not visible to the naked eye, a convex lens with a slight focus distance is used to make them look bigger and clearer. This convex lens is called magnifying glass or a reading glass or a simple microscope. This lens is usually encased in a wooden or plastic frame. However, this lens does not provide much magnification.
