What type of image does a concave lens produce?
no image
only a virtual image
both real and virtual images
only a real image
only a virtual image
A concave lens produces only a virtual image.
A concave lens produces only a virtual image. To understand why, let's look at the properties of a concave lens.
A concave lens is thinner in the middle and thicker at the edges. When light passes through a concave lens, it diverges or spreads out. This means that the rays of light do not converge to a single point like they do with a convex lens.
As a result, when the incident rays of light pass through a concave lens, they appear to come from a specific point on the same side of the lens as the object. This apparent point of origin is called the virtual image. The virtual image can be seen when looking through the lens from the side opposite to the object placed in front of it.
In summary, a concave lens does not form a real image. It produces only a virtual image.
