Question

Draw a diagram of 'image formed by concave lens'.

Hint:

Remember: A concave lens always forms a virtual, erect, and diminished image. The image is formed on the same side of the lens as the object.

Answer 1

A concave lens is a diverging lens. It is thinner at the center and thicker at the edges. When parallel rays of light pass through a concave lens, they diverge after passing through the lens. These diverging rays appear to come from a point behind the lens. This point is where the virtual image is formed. In the diagram below, parallel rays of light (AB) are incident on the concave lens (L). After passing through the lens, these rays diverge. The diverging rays seem to originate from a point I behind the lens, which forms the virtual image. This image is upright, diminished in size, and located on the same side as the object. % The code below assumes you have an image of the diagram. You can replace the image path with your actual image path. \includegraphics[width=8cm, height=8cm]concavelensᵢmage.png - Virtual: The image cannot be captured on a screen because the light rays do not actually converge; they only appear to converge at a point behind the lens. - Erect: The image has the same orientation as the object. - Diminished: The image is smaller than the object. - On the same side as the object: The image is formed on the same side of the lens as the object, making it a virtual image.
