Question

A concave mirror has a radius of curvature of 5.6 cm. (a) Determine the object position for which the resulting imageis upright and three times the size of the object.
cm

(b) Draw a ray diagram to determine the position of the image. (Usea negative number if the image is behind the mirror.)

(b) Draw a ray diagram to determine the position of the image. (Usea negative number if the image is behind the mirror.)
cmfrom the mirror.

Explanation / Answer

given the radius of the curvature is R = 5.6 cm so the focal length of the mirror is f = 2.3cm                      the magnification is m = 3 let the object and image distance be doand di then we have     m=   - di / do             so          di = -3  do from the lens equation we have                             1/f = 1/ do + 1/ di plug in the values and calculatefor  do then we have     m=   - di / do             so          di = -3  do from the lens equation we have                             1/f = 1/ do + 1/ di plug in the values and calculatefor  do
