Final answer:
The question is about determining the focal length of a concave mirror that forms an inverted image four times larger than the object. The mirror equation, which connects the object distance, image distance, and focal length, is used for this purpose.
Step-by-step explanation:
The problem involves a concave mirror forming an inverted image that is four times larger than the object itself. The magnification (m), which is the ratio of the image size to object size, is indicated by a negative sign as the image is inverted. Thus, m = -4. According to the mirror equation 1/f = 1/do + 1/di, where f is the focal length, do is the object distance and di is the image distance, we can substitute m as the ratio of -di to do. Given that total distance between the object and the image is 0.6 m, and since m = -di/do, we get di = -0.48 m and do = 0.12 m. Substituting these values in the mirror equation, we can calculate the focal length f.
