In Example 9.1 (convex mirror, bus at 5.00 m, R = 3.00 m), the magnification is calculated to be approximately +0.23. What does this tell us about the image?
It is real, inverted, and larger than the object
It is virtual, erect, and smaller than the object (by a factor of 0.23)
It is real, erect, and the same size as the object
It cannot be determined from magnification alone
