A dice is place with one of its edges parallel to the principal axis between the principal focus and the centre of curvature of concave mirror. Then the final image has the shape of:
A. cube
B. rectangular parallelepiped
C. barrel shape
D. spherical
The final image will have the edges perpendicular to principal axes larger than that of the dice. Thus, the shape of dice will be same but with different dimensions like a rectangular parallelepiped.
