A concave spherical mirror has a radius of curvature of magnitude 21.0 cm. (a) Find the location of the image for the following object distances. (If there is no image formed enter "NONE".) object distance (cm) image distance (cm) 39.6 21.0 10.5 X Check your use of the mirror equation. What quantity is zero in this equation for this case? (b) For each case, state whether the image is real or virtual. object distance (cm) real/virtual 39.6 21.0 10.5 real real There is no image formed. (c) For each case, state whether the image is upright or inverted. object distance (cm) real/virtual 39.6 21.0 10.5 inverted inverted There is no image formed. (d) Find the magnification in each case. (If there is no image formed enter "NONE".) object distance (cm) magnification 39.6 21.0 10.5 X K location in front of the mirror in front of the mirror There is no image formed
