Consider the following statements:1. Emission of light by objects.2. ...
Understanding the Phenomenon of Seeing Objects
Seeing objects involves several optical phenomena, primarily focusing on how light interacts with those objects. Let’s explore the given statements:
1. Emission of Light by Objects
- Certain objects, like the sun or a light bulb, emit their own light, allowing us to see them directly.
- This phenomenon is crucial in understanding how we perceive brightly lit objects.
2. Reflection of Light by Objects
- Most objects do not emit light but reflect light from other sources (e.g., sunlight or artificial lighting).
- Reflection is essential for visibility; without it, we wouldn't see most objects around us, as they rely on reflecting light rays into our eyes.
3. Dispersion of Light
- Dispersion occurs when light is separated into its constituent colors, as seen in a prism.
- While dispersion is an interesting optical phenomenon, it is not directly related to the ability to see objects. Instead, it pertains to how light behaves rather than how we perceive objects.
Conclusion
Given the explanations:
- Statement 1 (Emission) and Statement 2 (Reflection) are directly related to seeing objects.
- Statement 3 (Dispersion) does not contribute to the perception of objects in everyday scenarios.
Thus, the correct answer is option 'A' (1 and 2 only), as these two phenomena are integral to how we see and identify objects around us.

Consider the following statements:1. Emission of light by objects.2. ...
- To be able to see an object, it is necessary for light from the object to reach the eyes. This light can reach the eyes through emission or reflection.Objects which emit light of their own are called luminous objects, while objects which do not emit light are called non luminous.
- The phenomenon of splitting of white light into its constituent colours is called dispersion. Rainbow is a natural phenomenon caused by dispersion of light. Dispersion is not responsible for the sight of objects.
