Images Formed By Lenses Trivia Quiz

Let’s start the quiz

Lenses are mainly used to make images of an object view, the word lens is derived from a lentil bean from the Latin language, most lenses are spherical lenses, their two surfaces are parts of spherical surfaces. In general, there are two types of spherical lenses. So, the lens that binds two spherical surfaces facing outward is known as a convex lens, while the lens that binds two spherical surfaces as they are curved inward is known as a concave lens, Convergent lenses can produce both real and virtual images whereas diving lenses can only produce virtual images, the line joining the centers of the spheres forming the lens surfaces is called the axis of the lens, usually the lens axis of the lens. The greater the effect a lens has on the rays of light, the more powerful it is said to pass through the physical center. So let's start this quiz and know interesting facts about the lens.
