An image formed by a concave ___________ cannot be obtained on a screen.

An image formed by a concave lens cannot be obtained on a screen.


Concave lenses create only virtual images . After the rays are refracted, they never converge and so there will be no real images . All concave lens images will be upright, virtual, and diminished, and can be found between the F and the lens .

  • A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge
  • Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/ lens than the focal point, and this real image is inverted.
