The correct answer is: Real, virtual
- A real image is obtained when light rays from an object appear on the screen after being reflected or refracted. These images can be obtained on the screen.
- The rays on the screen must intersect to get an image on the screen, but the virtual image is formed by the rays not intersecting. Therefore, it is not possible to get a virtual image on the screen.
