WebConstruction and parts. Compasses are usually made of metal or plastic, and consist of two "legs" connected by a hinge which can be adjusted to allow changing of the radius of the circle drawn. Typically one leg has a spike at its end for anchoring, and the other leg holds a drawing tool, such as a pencil, a short length of just pencil lead or sometimes a pen. WebIt shows that the focal length of a thin lens depends only of the radii of curvature and the index of refraction of the lens and that of the surrounding medium. For a lens in air, n 1 = 1.0 and n 2 ≡ n, so the lens maker’s equation reduces to. 1 f = ( n − 1) ( 1 R 1 − 1 R 2). 2.21.
