1.	An object is placed at the following distances from a concave mirror of focal length 15 cm, turn by turn(a) 35 cm(b) 30 cm(c) 20 cm(d) 10 cmWhich position of the object will produce :(i) a magnified real image ?(ii) a magnified virtual image ?(iii) a diminished real image ?(iv) an image of same size as the object ?
Answer» (i) A magnified real image – When the object is placed at a distance of 20 cm from the mirror i.e., between focus and centre of curvature. (ii) A magnified virtual image – When the object is placed at a distance of 10 cm from the mirror i.e., within its focus. (iii) A diminished real image – When the object is placed at a distance of 35 cm from the mirror i.e. beyond the centre of curvature. (iv) An image of same size as the object – When the object is placed at a distance of 30 cm from the mirror i.e., at the centre of curvature.

Answer»

(i) A magnified real image – When the object is placed at a distance of 20 cm from the mirror i.e., between focus and centre of curvature.

(ii) A magnified virtual image – When the object is placed at a distance of 10 cm from the mirror i.e., within its focus.

(iii) A diminished real image – When the object is placed at a distance of 35 cm from the mirror i.e. beyond the centre of curvature.

(iv) An image of same size as the object – When the object is placed at a distance of 30 cm from the mirror i.e., at the centre of curvature.
