As noted in the book, these ray tracing rules are an approximation. For this approximation to be accurate, the paraxial rays should be closer to the axis, and the object should be small compared to the mirror radius. • We've drawn these examples in an exaggerated manner, because it is easier to see. • This is still a very
Converging (Concave) Mirror. A converging mirror is one that is spherical in nature by which it can FOCUS parallel light rays to a point directly in front of its surface. Every spherical mirror can do this and this special point is at a “fixed" position for every mirror. We call this point the. FOCAL POINT. To find this point you MUST

mirror. The most commonly used type of curved mirror is the spherical mirror. The reflecting surface of such mirrors can be considered to form a part of the surface of Fig. 10.12 (a). Hence convex lenses are called converging lenses. Similarly, a double concave lens is bounded by two spherical surfaces, curved inwards.
Types of Mirrors. Figure 1 shows the three types of mirrors we will consider. All of them are segments of spheres centered on a horizontal axis. There is an .. Diverging Lens. O. I. Figure 6: The figure shows a typical converging lens (with focal length f = +50) and a diverging lens (with focal length f = ?50). The object is O

LENS AND MIRROR CALCULATIONS. 2.1 Introduction. The equation that relates object distance p, image distance q and focal length f is .1. 1. 1 f q p. = +. 2.1.1. Or is it? Should that not be a minus sign on the left hand side? Or should it be a plus sign for mirrors and minus for lenses? (“More for a Mirror; Less for a Lens."?)
13 Sep 2012 To find the normal to a curved surface at a point where a ray hits that surface (and will be reflected or refracted). – First draw a tangent line to the curve. (or tangent plane to the surface). – The normal is perpendicular to that line or plane and going through the point. – Once you have drawn the normal you.
*In 1678 the great Dutch physicist Christian Huygens (1629-1695) wrote a treatise called. Traite de la Lumiere on the wave theory of light, and in this work he stated that the wavefront of a propagating wave of light at any instant conforms to the envelope of spherical wavelets emanating from every point on the wavefront at
