Question

A concave mirror has F= 10cm where should an object be pieced in front of this concave mirror as to obtain an image which is real, inverted and same size of the object?​

Answer 1

Answer:

When the image fromed by a concave mirror is inverted and of the same size as the object, then the object must be placed at its centre of curvature ( C). Now, the centre of curvature of a concave mirror is at a distance of 'twice the focal length' of '2f'. Here, <br> Focal length, f=10 cm <br>

<br> =20 cm <br> Thus, the object should be placed at a distance of 20 cm in front of this concave mirror.

Answer 2

Answer:

Wherer should and object be placed in front of this concave mirror so as too obtain an image which is real, inverted and same size as the object ? Thus, the object should be placed at a distance of 20 cm in front of this concave mirror
