Converging Lenses
Converging lenses are lens that converge light rays at the focal point
Focal point -: Focal point is the point where rays reflect or refract to meet in a particular point
Focal length -: Focal length is the distance between the lens and focal point
Converging lens logic
Convex lens converge light because of their curved shape
the term converge means that everything meets in one point
In a convex lens, the lens are thicker in middle and small in edges
When light meets in edges they converge to meet in focal point
When light hits the thicker part of the converging lens, it travels in a straight line
Sight Formation On Converge Lens
Lens make look objects more bigger when the light from far away, meets the lens shown in figure, the light focuses on one point
As you can see the light enters the retina on a particular focal point, the converging lenses gathers many light rays to get into one big image
As the object moves closer, when it comes to a converge lens they become smaller in your vision, as less light rays converge
These information are basic, Go for advance studies like refraction, where the image will form etc
