CASE STUDY : Light is a form of energy which induced sensation of vision to our eyes. It becomes visible when it bounces off on surface and hits our eyes. Regular reflection takes place through a smooth polished surface. The mirror outside the driver side of the vehicle is usually a spherical mirror and printed on such mirror is usually the warning "Vehicles in this mirror are closer than they appear". (i) What is the reason for this warning written on the mirror ? (ii) Draw a ray diagram showing the image formation in such kind of mirror. (iii) State two positions in which a concave mirror produces a magnified image of a given object. (iv) How is linear magnification it related to object distance and image distance ?
