Question

Irrespective of the position of the object on the principal axis, a concave lens always forms an image of nature

• A. real, invert
• B. real, erect
• C. virtual, erect
• D. Does not form any image

Answer 1

The Correct Option is C

Concave lenses are diverging lenses, meaning they spread out parallel rays of light. When an object is placed in front of a concave lens, the rays of light coming from the object diverge after passing through the lens. These diverging rays appear to originate from a point closer to the lens than the actual object. 

This is why the image formed is: 

Virtual: The light rays do not actually converge to form the image. Instead, the image is formed by the apparent intersection of the diverging rays' extensions behind the lens. 
Erect: The image is oriented in the same direction as the object. 
Diminished: The image is smaller than the object. The position of the object only affects the size of the image, not its virtual and erect nature.
