Question

sperical mirror forms a real and inverted image of same size as object at a distance of 40 cm from the mirror find the radius of curvature of the mirror​

Answer 1

Answer:

this will help you to find answer

Explanation:

When an object is placed at a distance of 40 cm from a concave spherical mirror, the magnification produced is 1/2, where should the object be placed to get a magnification [Ans.

Answer 2

Answer:At 40cm.

Explanation:When an object is placed at radius of curvature ,then the image will again get at same point with inverted and also it is real image.

So in a concave mirror , the object is placed at 40cm, then image also get at the same point.

Radius of curvature=40cm
