A shopper standing 3.0 m from a convex security mirror sees his image with a magnification of 0.25. (a)What is the distance of the image from the shopper? (b) Where Given: Required d, - m = -m is his image located? Equation a) image distance (d)= ? b) focal length a) md/d multiply both side by-d. (-d.)m(d./-dd) Solution Substitute the given and calculate the answer.: = (-d.)m a. the distance of the image is -m or -cm di = b) 1/f = 1/d.+ 1/d. 1/f (d.+d)/(d.d.) Get the reciprocal of both side of the equation (1/f (d.+do)/(d.d.)) f (d.d)/(d.+da) Answer b. the focal length is -m or -cm f= Now try to answer a word problem below about concave mirror on your own. 2.
