Reading Activity
Ray diagrams can be used to explain how images are formed by curved mirrors and the characteristics of these images.
The reflecting surface is represented by a straight line and a small curve is used to show the type of the mirror.
The object is represented by a straight line perpendicular to the principal axis with an arrow to show the tip.
The pole of the mirror is taken as the intersection of principal axis and the mirror line.
Define the following terms as used above.
1. principal axis
2. pole
