Question

The image of an object in a concave

mirror is erect and four times the
size of the object. If the mirror has a
radius of curvature of 48 cm, find the
position of the object.
O 12 cm
16 cm
O 18 cm

Answer 1

The position of the object in a concave mirror with a radius of curvature of 48 cm is 16 cm.

Step-by-step explanation:

To determine the position of the object, we can use the mirror equation:

1/f = 1/v - 1/u

Given that the image is four times the size of the object (magnification, M = 4), we know that:

M = -v/u

Substituting the given values into the equation and solving for u, we find that the position of the object is 16 cm.
