- A convex spherical mirror has a radius of curvature, R = -16.8 cm. If an image formed by reflection is to have a magnification of 0.489, at what distance in centimeters should an object be placed from the mirror?A concave spherical mirror has a radius of curvature, R = 18.2 cm. If an object is placed 53.4 cm in front of the lens, what is the magnification of the image produced?You have a concave spherical mirror (the same holds if you had a convex mirror) If the value of q(the distance from the image to the mirror along the principal axis of the mirror) is 1.45m and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 4.11m, what is the focal length of the mirror? The magnification equation and the sign convention for q imply that real images of real objects are always inverted (if both p and q are positive, m is negative); virtual images of real objects are always upright (if p is positive and q is negative, m is positive). Keeping the signs of p and q straight in your mind is the most challenging aspect of mirrors (and lenses). Fortunately, table 23.2 summarizes when p and q are positive and when they are negative.
