WebIf the object is at radius, the image formed by the concave mirror is inverted, real, and of the same size as the object. Here, focus f = 15 cm. The size of its image is equal to the size of the object. So, the distance of the object must be twice of focal length (or at radius). So, image must be formed at r = 2f = 2 × 15 cm = 30 cm. WebA covering lens and a spherical mirror are with their principle axis coinciding . Their separation equal 40 cm . A point source S is placed on the principal axis at a distance of 12 cm from the lens as shown in the figure . It is found that the final beam comes out parallel to the principal axis , Focal length of the lens equals 15 cm .
