Introduction
Images formed by lenses are either virtue or real. A converging lens forms a real image
while a diverging lens forms a virtue image. When a beam of light is incident to the converging
lens with ray parallel to the central axis of the lens the rays converges at a point called focal
point (Camacho, 2002). The focal length is the distance between the focal point and the center of
the lens. The focal length is taken as positive for a converging lens and negative for a diverging
lens. When a beam of light is incidence to a diverging lens the rays diverge as they leave the
lens. The outgoing rays behave as if they are emerging from a common source. This point is the
focal point of the diverging lens. The equation 1 shown below is relationship between the radius
of curvature, refraction index and the focal length of a given lens.

Where:
F = focal length, n = refraction index,
R = radius of curvature
The distance of the object from the lens is denoted as p while that of the image to the lens is
denoted as q. The relationship between the two distances and the focal length is given by
equation 2 below
