THE PHYSICS CAFE                       CHAPTER TEN - LIGHT - REFLECTION AND REFRACTION   1.10 Sign Convention for Spherical Mirrors**                                                              We will have to use some sign convention for solving the mirrors related problems is called sign convention . Assume origin of Cartesian coordinate system is concentric with pole of mirror and the object is placed at left side of mirror so that light ray fall on mirror from left-hand side. Then following conventions are All the distances are measured from pole. All the distance measured right sides of the pole are taken as positive. All the distance measured left sides of the pole are taken as negative. All the distance measured above the pole (principal axis...

Always place the object left side of mirror. Take two light rays from the head of object. One parallel to principal axis and second incident at pole. Incident light ray parallel to principal axis will always pass through focus. Incident light ray falling at pole will always reflected at the angle equal to incidence angle. Image will be formed at the point where bot...

THE PHYSICS CAFE                                                        CHAPTER TEN LIGHT - REFLECTION AND REFRACTION   1.05 Spherical Mirror and their Identification and Related terms**                                         1 Spherical Mirror : A curved and smooth piece of glass which is silver metal polished from one side. These are also called curved mirror due to their shape is curved.   Hint: For this type of mirror the piece of glass is cut from hollow sphere of glass.   Types and  Identification Types of spherical mirrors...
