Concepts Of Physics MCQ Edition [Volume 1]PhysicsGeometrical Optics
Identify the correct statement among the following.
Options
- AIf the incident rays are converging, the object is real.
- BThe image of a virtual object is defined as a virtual image.
- CIf the final rays are converging, a real image is formed.
- DA virtual image implies that the corresponding object is virtual.
Correct answer
C. If the final rays are converging, a real image is formed.
Step-by-step solution
An object is defined by the incident rays. If the incident rays diverge from a point, the object is real. If the incident rays converge towards a point, the object is virtual. Thus, converging incident rays correspond to a virtual object, making the first statement incorrect. An image is defined by the emergent (reflected or refracted) rays. If the emergent rays converge to a point, they actually intersect and a real image is formed. If the emergent rays diverge, they appear to come from a point and a virtual image
