Can you please explain how...well...how this works. Can you draw a diagram or something? It seems like if you use m=v/u and enter 25 cm for v, then you're saying that the image is 25cm from whatever the rest of the system is in the equation. m is the magnification of the lens, so when you arrive at the value for u, that seems like it should be saying that if you put the iron 8.3 cm from the lens, then it will project the image 25 cm from the lens. Not 25 cm in front of your eyes. I don't understand how the answer ends up applying to the distance to the eyes. Is there some algebra that needs to be done to link the distance from the image to the distance to the eyes? By the way, what do v and u stand for? I know they're distances, but what words do the letters represent?
Spherical refracting surfaces. When an object is placed 9.3 cm in front of a spherical refracting surface the image distance is -15 cm. The index of refraction of the refracting material is 2.7 and it is embedded in transparent material with index of refraction 2.0. Find (a) the radius of curvature r of the surface (including the sign) and determine whether the image is (b) real or virtual and (c) on the same side of the surface as object O or on the opposite side.
