Mark the correct options:

  • A
    If the incident rays are converging, we have a real object.
  • B
    If the final rays are converging, we have a real image.
  • C
    The image of a virtual object is called a virtual image.
  • D
    If the image is virtual, the corresponding object is called a virtual object.

Answer

  1. If the final rays are converging, we have a real image.

Explanation:

This is because a real image is formed by converging reflected/ refracted rays from a mirror/ lens.
