The concave mirror mounted in its holder is moved to and fro in front of the screen until a sharp image of the cross wire of the ray box is formed on the screen adjacent of the object.The distance between the mirror and the screen was measured as 30cm since the radius of curvature r=2fo then half is distance

i)It is virtual
ii) It is enlarged or magnified i.e. twice or two times bigger as the object(m=2)
