Its close to real world entity..
An object may represent a real-world object (in as much or as little detail as necessary), or it may be a completely imaginary object, such as conceptual object like a shape (rather than specific type of shape like a square). But regardless of what they represent, they are not physical objects that we can pick up and touch; they only exist in a computer's memory. Thus an object is a software unit.
There are two types of languages. Procedure oriented language and object oriented langugae. An object oriented langugae is quite impresses from real world environment. it says that for example a classroom is full with chairs then that class is a class of object oriented and those chairs are object... Basically this makes programing very easy and short... Hope this answer was of some help...
Objects are key to understanding object-orientedtechnology. Look around right now and you'll find many examples of real-world objects: your dog, your desk, your television set, your bicycle. Real-world objects share two characteristics: They all have state and behavior. Dogs have state (name, color, breed, hungry) and behavior (barking, fetching, wagging tail). Bicycles also have state (current gear, current pedal cadence, current speed) and behavior (changing gear, changing pedal cadence, applying brakes). Identifying the state and behavior for real-world objects is a great way to begin thinking in terms of object-oriented programming.
A physical object is a real-world entity -- one you can physically sense either by seeing it, touching it, smelling it, hearing it or tasting it. By contrast, a virtual object is one we can only imagine. In object-oriented programming languages such as C++, all objects are virtual entities that can be used to represent a physical entity or an imagined entity, or a combination of both, either in whole or in part.

If you asking where you'd find them in the real world - Binoculars and telescopes are two examples.
A class is a blueprint or a detailed description of a real-world object. An object is an instantiation of a class into memory.

A class in object-oriented programming represents a blueprint for creating objects that share common characteristics and behavior in the real world. It defines the attributes and methods that objects of that class will have.

Contrast is the difference in light and/or gloss that hits an object distinguishable. In ocular perception of the real world, contrast is resolved by the difference in the color and brightness of the object and other.
A concave mirror could be used, as it can produce a real image that is the same size as the object when the object is placed at the focal point of the mirror.
[object Object]
The term virtual object refers to computer simulations of real objects; it could be described as a technological illusion. Reality, in comparision, is what it appears to be. Not only does it look like a chair (for example) but you can actually sit in it. Whereas, a real person does not sit in a virtual chair, although a virtual person can do so.
