What effect does a concave mirror have when the object is between the focal point and the mirror?

When an object is positioned between the focal point and a concave mirror, the mirror forms a diminished, virtual, and upright image. This phenomenon occurs because the light rays reflecting off the mirror diverge in such a way that they appear to come from a point behind the mirror.

In this case, since the object is closer to the mirror than the focal point, the light rays reflecting off the surface of the concave mirror do not converge in front of the mirror. Instead, they reflect and diverge, making it seem as though they are coming from a point behind the mirror. As a result, the image appears to be upright and virtual, meaning it cannot be projected onto a screen. Additionally, since the object is near the mirror, the image appears smaller than the actual object, hence the term "diminished."

This unique behavior is a fundamental aspect of how concave mirrors operate in this particular arrangement, reinforcing the properties of reflection and image formation related to concave mirrors specifically.
