A double convex lens, or converging lens, focuses the diverging, or blurred, light rays from the distant item by refracting (bending) the rays two times. In the front aspect of the lens, the rays are bent towards the traditional (the perpendicular to the floor) since the glass is often a denser medium when compared to the air, and, at the again aspect from the lens, the rays are bent faraway from the traditional as the rays pass in the fewer-dense medium of your air.
Cite Even though just about every energy has become built to stick to citation design procedures, there might be some discrepancies. Remember to make reference to the right design guide or other sources In case you have any thoughts. Select Citation Type
