Which of the following statements is true for a concave mirror?a) It always forms a virtual and upright image.b) It always forms a real and inverted image.c) It depends on the position of the object.d) It does not form an image.

The correct answer is c) It depends on the position of the object.

To understand why, let's break down the characteristics of a concave mirror:

1. A concave mirror is a curved mirror with a reflective surface that curves inward, like the inside of a spoon.

2. When an object is placed in front of a concave mirror, the mirror reflects the light rays coming from the object.

3. The reflected light rays converge or come together at a specific point called the focal point (F) of the mirror.

Now, let's consider the different scenarios:

• If the object is placed beyond the focal point (F) of the concave mirror, the reflected light rays will converge and form a real image. This real image will be inverted (upside down) and can be projected onto a screen.

• If the object is placed between the focal point (F) and the mirror, the reflected light rays will still converge, but this time they will diverge after crossing each other. As a result, the image formed will be virtual (not able to be projected onto a screen) and upright (not inverted).

• If the object is placed very close to the concave mirror, the reflected light rays will diverge before they even cross each other. In this case, no image will be formed.

Therefore, the statement that is true for a concave mirror is c) It depends on the position of the object.
