Converging Lenses
Steps:
1.draw/choose a point on top of the object and draw 3 incident rays traveling to the lens.The first ray should be perpendicular to the lens,then draw the refracted ray that passes through the focal point.The 2nd ray should be drawn passing through the focal point,then the refracted ray should be parallel to the principal axis. . Draw the third incident ray such that it travels directly to the exact center of the lens.
2. Get the intersection of the refracted image.
