WebFeb 20, 2011 · no the formula 1/f=1/di- 1/do is correct, because it is based on the sign covention for lenses where object distance (do) is always taken as negative for all real objects, but sal's formula is …
WebWithout signs we have to explicitly mention we're dealing with a concave mirror, or a convex mirror, or the images in front of the mirror, or the images behind the mirror. But with Signs these things are done mathematically. For example, if I just say negative focal length it …
WebConcave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object. The closer the object comes to the focal point (without passing it), the bigger the image will be.
