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.
0.5 cm
1.0 cm
1.5 cm
2.0 cm
Vysvětlení
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.
