magnifying glass
Transcript: The simple lens of the magnifying glass is using the retina and lens of your eye to create a virtual image, that appears to be closer to the convex lens of the magnifying glass Modern magnifying glasses are double-convex lenses and they make the objects appear larger. The lens is convex on both sides, ie. thicker in the middle. When viewing objects the light rays are bent towards the center of the lens, making the object look larger than it is to the eye Each magnifying glass has a focal length, which is the distances from the optical center of the lens to the point where the light rays converge History of Magnification During the 16th century, the first primitive microscopes were invented using multiple lenses HOW DOES MAGNIFYING G S WORK? LAS If you look through the lens at the object, you'll see an image that is right-side up and larger than the original The Egyptians had discovered an almost clear crystal, called obsidian that was used to view small objects Historians seem to agree that the Romans were the first to discover glass in the first century AD
