SECTION B 1. Define the principal focus of a concave mirror
b. Name a mirror that can give an erect and enlarged image of an object.
a. The radius of curvature of a spherical mirror is 20 cm. What is its focal length?
c. Why do we prefer a convex mirror as a rear-view mirror in vehicles?
2. A converging (concave) mirror has a focal length of 5.0 cm. A 1.0-cm tall candle is
placed at a distance of 2.5 cm in front of the mirror.
(a) By drawing a ray diagram, find the location of the image formed by the
converging mirror. State whether the image is real or virtual, upright or inverted,
(b) Using the mirror and magnification equations, verify your results from (a
and larger, smaller, or the same size as the object (candle).​
