Question
An object of size 2.0 cm is placed perpendicular to the principal axis of a concave mirror. The distance of the object from the mirror equals the radius of curvature. The size of the image will be ___________.Select an answerA0.5 cmB1.5 cmC1.0 cmD2.0 cm
Solution
The size of the image formed by a concave mirror when the object is placed at the center of curvature (which is the case here since the object distance equals the radius of curvature) is the same as the size of the object. This is because the magnification in this case is -1 (negative indicates that the image is inverted).
So, the size of the image will be 2.0 cm.
Therefore, the correct answer is D2.0 cm.
