Hello, here is the problem i am having trouble with. The sun falls on a concave mirror and forms an image 3 cm from the mirror. If an object 24mm high is placed 12 cm from the mirror, where will its image be formed? So far, i have decided that since 1/f = 1/do + 1/di...(adsbygoogle = window.adsbygoogle || []).push({});

1/f = 1/do + 1/3 = 1/12 + 1/di

I also decided that hi/2.4 = -di/12... The problem is...even if i solve for di in terms of hi and plug that into my first equation i dont have enough information to solve for do. Im stuck and this problem is due tomorrow... please help

thanks
