An object 2.0 cm high is placed at the radius of curvature of a concave mirror such that it is perpendicular to the principal axis of the mirror. Determine the height of the image.
A
0.5 cm
B
1.0 cm
C
1.5 cm
D
2.0 cm
Verified Correct Answer: D.
Physical Principles & Numerical Solution
When an object is placed at the centre of curvature of a concave mirror, an image that is the same as the object will be formed. Therefore, the height of the image is 2.0 cm.
