Question

A concave mirror gives real , inverted and small size IMAGE if the object is placed :

(a) At F

(b) At infinity

(d) Beyond infinity

Answer

The correct option is : (b) At infinity

When an object is placed at infinity, highly diminished real and inverted image is formed . The image is formed at Focus (F)

About other options

(a) When an object is placed at Focus (F) , image formed is real and inverted but is highly enlarged .

(c) When an object is placed at CENTRE of curvature (C) , the image formed is real and inverted but is of same size with the object

(d) Beyond the LEVEL of infinity is never calculated . This option is probably provided to confuse the student.
