Converging Lens or Convex Lens
Converging Lens or Convex Lens
It is the lens which is thicker in the middle than at the edges. A beam of parallel rays of light falls on a convex lens from the left side. After passing through the convex lens, the beam of parallel rays of light converges at a point . Hence, a convex lens is a converging lens.
Image formed by convex lens :
The nature of the image formed by a convex lens varies as the distance of the object from the lens changes. When an object is placed at a far off distance from the convex lens, then the image formed by the convex lens is real, inverted and much smaller than the object.
When we place the object closer to the lens then the image formed will be erect and magnified.
