The image by a concave mirrors of same size when object is placed at………………

A concave mirror forms image inverted and equal in size, when object is placed at…… .

An object is placed at a distance of 40 cm from a concave mirror of focal length 15 cm.If the objects is displaced through a distance of 20 cm towards the mirror,by how much distance is the image displaced.

When does a concave mirror form a vritual image?

Draw a ray diagram to show the image formation by a concave mirror, when the object is kept between its focus and the pole.

The image formed by a concave mirror is observed to be virtual, erect and larger than object,where should be the position of the object?

When the image formed by a concave mirror is at infinity then what is the position of the object?

A concave mirror of focal length 20 cm and a convex mirror of focal length 15 cm are placed 50 cm apart,such that the two mirrors face each other .An object is placed exactly midway betwen them.Find teh nature and position of the image formed by reflection first at the concave mirror and then at the convex mirror.

If the radius of curvature of convex mirror is 40 cm and size of object is twice as that of the image,then the object distance is
