The magnification produced by a spherical mirror is +0.75. The image is:
‘Virtual, erect and diminished
The magnification (m) produced by a spherical mirror is given by the formula:
m = - (Image Height / Object Height) = (Image Distance / Object Distance)
Given the magnification is +0.75, it indicates that the image is virtual and erect. For mirrors, a positive magnification generally means the image is virtual and erect since real images produced by mirrors are inverted, leading to a negative magnification.
Furthermore, a magnification value less than 1 (m = +0.75) suggests that the image is smaller than the object, thus it is diminished.
Based on this analysis, the image is virtual, erect, and diminished.
