Question

the magnificiant factor of spherical mirror is -0.45.what does it signify​

Answer 1

Answer:

The magnification produced by a spherical mirror is  −0.45.  What does this mean?

Magnification is the ratio of the height of the image and the height of the object.

The magnitude of the magnification is  0.45.  

⇒  The size of the image is the same as the size of the object.

The sign of the magnification is negative.

⇒  The image is inverted.

⇒  The image is real.

For a spherical mirror, magnification is also the negative ratio of the distance of the image from the mirror and the distance of the object from the mirror.

⇒  The distance of the image from the mirror is the same as the distance of the object the from the mirror and the object and image are in the same side of the mirror.

⇒  The distance of the object from the mirror is twice the focal length.
