Question
Opaque objects with highly smooth and polished surface _____ most of the light that falls on its surface.
- Transmit
- Absorb
- Reflect
- All of the above
Hint:
Light waves incident on a surface or object are either transmitted through the object or reflected from the surface. The amount of light absorption also depends on the nature of the surface. That is, whether they are opaque ,smooth or transparent.
The correct answer is: Reflect
- Opaque objects mean that these objects do not let light through. So when a ray of light hits an opaque object, it creates a shadow.
- Also, absorption is greatest for opaque objects. A polished material or surface actually reflects light. In other words, we can say that when a ray of light hits a surface, it bounces off.
- In either case, the surface absorbs some light. However, on polished surfaces such as mirrors, this is much less.
- Therefore, the process of reflecting light back is called reflection.
