An upside-down image formed where light rays meet is called a

Real Image Focal Point Optical Axis Lens

Correct Answer:

Real Image

Explanation:

A real image is formed when light rays actually converge to a point in space. Because the rays cross, the image you’d see (or project onto a screen) is inverted relative to the object. This contrasts with a virtual image, which is formed by diverging rays that only appear to originate from a point and cannot be projected, and is usually upright. The focal point is simply where rays converge after reflection or refraction, the optical axis is just the reference line through the system, and a lens is the device that bends the light, not the image itself. So an upside-down image formed where light rays meet is a real image.
