in concave mirror. :-

when an object is placed at the focus of a concave mirror the image formed is :-

1 :) at infinity.

2:) real and inverted.

3:) highly magnified or highly enlarged .

in figure :-

THE OBJECT "AB "HAS BEEN PLACED AT THE FOCUS (F) OF THE CONCAVE MIRROR.

NOW THE PARALLEL RAY OF LIGHT (AD) COMING FROM THE OBJECT ) GETS REFLECTED AT" D " AND PASSES THROUGH THE FOCUS F, GIVING US THE REFLECTED RAY "DX" . A SECOND RAY OF LIGHT " AE" PASSING THROUGH THE CENTRE OF CURVATURE C , IS REFLECTED BACK ALONG THE SAME PATH GIVING US ANOTHER REFLECTED RAY" EY" . WE FIND THAT THE REFLECTED RAYS" DX" AND "EY" ARE PARALLEL TO ANOTHER . THESE || PARALLEL RAYS WILL INTERSECT (OR MEET) AT A FAR OFF DISTANCE OF FROM AN IMAGE ' AT INFINITY' AND SINCE IMAGES IS FORMED AT INFNITY .
