Where must the object be placed in front of a concave mirror of focal length 12 cm in order to get the magnification of image is 1?

The object should be placed at a distance of 24 cm to from the lens (on the left side).

What distance from a concave mirror of focal length is 12 cm?

Focal Length = 12 cm. Distance = 60 cm. ( Since, the image is formed on the wall and the distance between the wall and mirror is 35cm. ) [ And, the image is beyond 2f, so object has to be in between F & C ].

Where should the object of 4 cm height placed in front of concave mirror of focal length 12 cm and whose image should be 1 cm in height?

Answer: 9 cm infront of the mirror.

When an object is placed at 12 cm from the concave mirror having focal length 6 cm find the image distance?

If the image is virtual behind the mirror, then image distance is positive, So, object distance (u) = – 6cm. image distance (v) = 12cm.

When an object is placed at 12 cm in front of concave mirror of focal length 15cm What is the image formed real and inverted?

Answer Expert Verified 60 cm is the required answer.

At what distance from a concave mirror of focal length 12 cm must an object be placed in order that an image double its size may be obtained?

Thus, the object must be placed at a distance of 24 cm ( 2 × 12 ) from the converging lens.

What is the distance of a concave mirror?

The object should be placed at a distance of 6.66 cm on the left side of the mirror.

Where should an object be placed in front of a concave mirror of focal length 20cm?

so the object must be placed 30 cm from the mirror. When an object is placed 20 cm from a concave mirror, a real image magnified three times is formed.

When an object is placed at a distance of 12 cm from a concave mirror the image is formed at a distance of 24 cm what will be the magnification?

Explanation: Image is inverted so magnification ratio should be negative. Image is formed at 24 cm from mirror in same direction of object.
