Question

You have a concave spherical mirror with a 10.9-cm radius of curvature. You place an object on the mirror\'s axis, 18.9 cm in front of the mirror. How far is the object's image from the mirror? (in cm)

If it can be determined, is the image real or virtual?

If it can be determined, is the image upright or inverted with respect to the object?

Answer 1

We have a mirror formula as

we have

Radius of curvature = 10.9 cm then Focal lenth = -5.45 cm

object distance = -18.9 cm then

So image will be at 7.66 cm in front of mirror.

Since the image is in the same side of mirror so the Image will be real.

Magnification of the mirror is given by

Since magnification is negative so the Image will be inverted
