Answer
| Real Image | Virtual Image |
|---|---|
| A real image is formed due to actual interaction of the rays refracted by the lens. | A virtual image is formed when the rays refracted by the lens appear to meet if they are produced backwards. |
| A real image can be obtained on a screen. | A virtual image cannot be obtained on a screen. |
| A real image is inverted with respect to the object. | A virtual image is erect with respect to the object. |
