2) An object on the axis of the lens or mirror may be imaged correctly, but off-axis objects may be out of focus. In a camera, this type of aberration would show up as a fuzziness near the sides of the picture when the center was perfectly focused. One way of decreasing aberration is to use a small-diameter mirror or lens, or block most of the light with an opaque screen with a hole in it, so that only light that comes in close to the axis can get through. Either way, we are using a smaller portion of the lens or mirror whose curvature will be more shallow, thereby making the shallow-mirror (or thin-lens) approximation more accurate.
The positive sign is used when both surfaces are curved outward or both are curved inward; otherwise a negative sign applies. The proof of this equation is left as an exercise to those readers who are sufficiently brave and motivated. 4* Refraction and the Principle of Least Time We seen previously how the rules governing straight-line motion of light and reflection of light can be derived from the principle of least time. What about refraction? In the figure, it is indeed plausible that the bending of the ray serves to minimize the time required to get from a point A to point B.
There are two possible approaches here. The approach we have been using so far is the more popular approach in textbooks: leave the equation the same, but attach interpretations to the resulting negative or positive values of the variables. g. that the value of di should be negative when the image is a virtual image formed by an inbending mirror. Positive and negative signs also have to be memorized for focal lengths. Ugh! It’s highly unlikely that any student has ever retained these lengthy tables in his or her mind for more than five minutes after handing in the final exam in a physics course.
