The point of intersection of the inclined rays is called object.
Objects are of two types.
- Real object: If the incident ray diverge from an object, the object is a real object.
- Virtual object: If the incident ray converge and appear to intersect at a point behind the mirror or lens, then the point is a virtual object.
The point of intersection of the corresponding reflected and refracted rays is called image.
Images are of two types.
- Real image: The point of intersection of the reflected or refracted rays is a real image.
- Virtual Image: If the rays diverge from a point after reflection or refraction, a virtual image is formed.
