1. The problem statement, all variables and given/known data If the object distance in the following picture were 8.0 m and the image distance were 2.0 m, and the object is 0.50 m tall, how tall is the image. Ho = 0.5 So = 2.0 Si = 8.0 2. Relevant equations Ho / Hi = So / -Si In order these variables are hight object, hight image, object distance and object image. 3. The attempt at a solution 0.5/ Hi = 2.0/8.0 This is where the problem occurs. How do I get Hi on one side of the equation? I don't know how to move the numerator to the other side of the equation... Please help... I think there is a very simple solution but, it is eluding me.
