An actual light bulb is shown below, with a concave mirror. The blue dot is the focal point of the mirror. What best describes the unseen image of this bulb? Light bulb and concave mirror A. Real, upside-down, and larger than the actual bulb. B. Real, upside-down, and smaller than the actual bulb. C. Virtual, right-side-up, and larger than the actual bulb. D. There is no image at all in this case.

The correct option is;

A. Real, upside-down, and larger than the actual bulb.

Explanation:

Here we have that the blue dot is at the focal point of the mirror which gives the focal point as -12

Therefore, the center of curvature of the concave mirror where assumed to be a spherical mirror is given as follows;

Center of curvature ≈ 2 × Length of focus

That is the location of the center of curvature ≈ -24

Hence the object is between the focus and the center of curvature

When an object is placed in between the focus and the center of curvature of a concave mirror, the image is real, upside-down and magnified.

it is A
