Concave Lens Image Characteristics

A concave lens is a diverging lens. It spreads out light rays that pass through it.

Regardless of the object's position in front of a concave lens:

• The lens always converges the light rays to form an image on the same side as the object.
• This image is formed between the optical center and the principal focus of the lens.

Key properties of the image formed by a concave lens are consistently:

• Virtual: The rays do not actually meet; they only appear to diverge from a point. This means the image cannot be projected onto a screen.
• Erect: The image is upright, oriented in the same direction as the object.
• Diminished: The image size is always smaller than the object size.

Therefore, a concave lens always forms a virtual, erect, and diminished image.

Final Answer Selection

Based on the consistent properties of image formation by a concave lens, the correct description is Virtual, erect, and diminished.
