An object 1.50 $\mathrm{cm}$ high is held 3.00 $\mathrm{cm}$ from a person's cornea, and its reflected image is measured to be 0.167 $\mathrm{cm}$ high. (a) What is the magnification? (b) Where is the image? (c) Find the radius of curvature of the convex mirror formed by the cornea. ( Note that this technique is used by optometrists to measure the curvature of the cornea for contact lens fitting. The instrument used is called a keratometer, or curve measurer.)

a) 0.1113b) 0.334 $\mathrm{cm}$c) 0.752 $\mathrm{m}$

but a magnification is given by height of the image. Right by height, off the object. I definitely have the support. 167 centimeter divided by I don't object. 1.5 sent me to this gives us on a fishing trip when 11 one year would be the eyes given by minus times magnification all times to you. So expression We just found these little 0.111 charms. Do you know we have a three centimeter. So excuse us a minus 0.32 entries in it minus sign indicates that image is behind the mirror. See we confined. Ready something region from the human equation That is one over. If when Woody I plus one more deal. So what from here? If can beard Amazing one would be I plus inward D'oh! More in this one we know our is equal to two times off f more off the f. Then we can substitute there any off f here. So our our will become here two one word D I plus moon war. Do you hope our minus one and substance saurian the Mord substituting the values two into one or zero point artisan 0.0.33 centimeter Waas one war three centimeter. My This one So so I'm trying this This part defying this part gives us here are to be the record 75 full centimeter.
