WebThe formula for spherical lenses is given by: 1/v – 1/u = 1/f This formula describes the relationship between object distance (u), image distance (v), and the focal length (f). … Web(a) If the image formed by a lens is diminished in size and erect, for all positions of the object, then the lens is a concave lens. (b) The point on the lens through which a ray of light passes undeviating is known as Pole. (c) Given, Object distance, u = -30 cm. Focal length, f =20 cm. i) Now, using the len’s formula,
Web24. aug 2016 · In the paraxial model of geometrical optics a lens can make all the infinitely many rays from an object point hitting the lens converge to a single infinitely small geometrical point. This is the definition of the image point in the world of paraxial optics. We can find the position of the image point by computing where the rays cross.
