Vedclass · Answer

(B) The rays from the Sun are parallel to the principal axis and converge at the focus $(F)$ of the concave mirror. Therefore,the focal length $(f)$ of the mirror is $15 \, cm$.For a concave mirror,the image size is equal to the object size when the object is placed at the center of curvature $(C)$.The center of curvature is at a distance equal to twice the focal length $(R = 2f)$.Thus,$R = 2 	imes 15 \, cm = 30 \, cm$.Therefore,the object should be placed at $30 \, cm$ in front of the mirror.

Rays from the Sun converge at a point $15 \, cm$ in front of a concave mirror. Where should an object be placed so that the size of its image is equal to the size of the object?
