Question

The image of an object placed in front of a convex mirror is formed at
1 point
(a) the object itself
(b) twice the distance of the object in front of the mirror
(c) half the distance of the object in front of the mirror
(d) behind the mirror

Answer 1

Answer:

To form an image of an object at itself we need to use concave mirror as it forms real image on same size of the mirror itself.

Answer 2

The image of an object placed in front of a convex mirror is formed at (d) behind the mirror.

Explanation:

• Convex mirror is a spherical mirror which has its bulged out part as the reflecting side.

• Convex mirrors are also called diverging mirrors.

• All the images formed by convex mirrors are virtual which means behind the mirror.

Only two variations in position of object is considered here:

1. Object at infinity produces image at focal point behind the mirror, the size of image is diminished and image is erect.
2. Object between infinity and pole of the mirror produces image which is diminished, erect and between pole and focus behind the mirror.
