Introduction:
The visibility of objects is primarily due to the reflected light from the objects. When light falls on an object, it interacts with the surface of the object in various ways, resulting in the perception of visibility. Let's explore this in more detail.
Explanation:
Visible light is a form of electromagnetic radiation that consists of a spectrum of different wavelengths. When light falls on an object, it interacts with the atoms and molecules present on the surface of the object. This interaction can lead to three possible outcomes: absorption, reflection, and refraction.
Absorption:
When light is absorbed by an object, it means that the object absorbs certain wavelengths of light and converts them into other forms of energy, such as heat. The absorbed light is not reflected or transmitted, making the object appear dark or invisible. Therefore, absorption of light does not contribute to the visibility of objects.
Refraction:
Refraction occurs when light passes through a transparent object and changes its direction. It happens due to the change in speed of light as it travels from one medium to another. While refraction can affect the path of light, it does not directly contribute to the visibility of objects.
Reflection:
Reflection is the key process that makes objects visible. When light falls on an object, some of it is reflected back into the surrounding environment. The reflected light carries information about the object's color and appearance, allowing our eyes to detect and perceive the object. The reflected light reaches our eyes, and the brain processes this information to create the sensation of visibility.
During reflection, the angle of incidence (the angle at which light strikes the object) is equal to the angle of reflection (the angle at which light is reflected). This phenomenon follows the law of reflection and allows us to see objects from different angles and perspectives.
Conclusion:
In conclusion, the visibility of objects is primarily due to the reflected light from the objects. When light falls on an object, some of it is reflected back, carrying information about the object's appearance. This reflected light is what allows us to see and perceive objects in our surroundings.

Option B is correct bcoz ---
light coming from the source falls on the object and reflects back into our eyes and our eye lens form an image of it which is virtual and inverted , but our brain interprets correctly.
