Concave Lens Image Characteristics

A concave lens is a diverging lens. Understanding its optical properties is key to determining the nature of the image it forms.

Image Formation by Concave Lens

For any object placed in front of a concave lens, the image formed has specific characteristics:

• Nature: The image is always virtual. This means the light rays do not actually converge; they only appear to diverge from a point behind the lens.
• Orientation: The image is always erect (upright), meaning it has the same orientation as the object.
• Location: The image is formed on the same side of the lens as the object.
• Size: The image is always diminished (smaller than the object).

Analysis of Options

Based on the properties above:

• Option 1 correctly states that the image is always virtual, erect, and on the same side as the object.
• Option 2 is incorrect because the image is typically diminished, not larger.
• Option 3 is incorrect because the virtual image is formed on the same side, not the opposite side.
• Option 4 is incorrect because concave lenses always form virtual images, never real images.
