Which describes an image that can be produced by a concave lens?

1)the image is real and smaller than the object.

2) the image is virtual and larger than the object.

3) the image is virtual and smaller than the object.

4) the image is real and larger than the object.

The image is virtual and smaller than the object is a description of an image that can be produced by a concave lens.

To add, concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). It is a type of diverging lens.

The correct answer to this question is : 3) The image is virtual and smaller than the object .

EXPLANATION:

A concave lens is a diverging lens. It is an optically transparent spherically refracting surface which is bulged at the edges and thinner at the centre.

Due to its shape, the rays of light are diverged when allowed to pass through this lens. Hence, the image formed by this lens is virtual and erect.

The magnification of image produced by the lens is less than one i.e the size of image is smaller than size of object.

Hence, the image formed by the concave lens is virtual,erect and diminished.

explanation:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
