Explanation:

When Abhishek looked at a lighted torch through an object, he could see a faint glow, but not the torch itself. Based on this observation, we can conclude that the object is translucent.

What is translucency?
Translucency is a property of materials that allows light to pass through, but scatters or diffuses it in the process. This results in a blurred or faint image being visible through the material.

Why is the object translucent?
In this scenario, Abhishek is unable to see the torch but can perceive a faint glow through the object. This indicates that the object allows some light to pass through it, but it scatters or diffuses the light, making the torch's image indistinct.

Difference between transparent, opaque, and translucent:
- Transparent: A transparent object allows light to pass through it without any significant scattering or diffusing. This means that objects can be seen clearly through a transparent material. Examples of transparent materials include glass and clear plastic.
- Opaque: An opaque object does not allow light to pass through it. When light encounters an opaque material, it is either absorbed or reflected, resulting in no transmission of light. Examples of opaque materials include wood, metal, and cardboard.
- Translucent: A translucent object allows some light to pass through it, but scatters or diffuses the light in the process. This causes objects to appear blurred or faint when viewed through the material. Examples of translucent materials include frosted glass, wax paper, and some plastics.

Conclusion:
Based on Abhishek's observation of seeing a faint glow but not the torch itself, we can conclude that the object he looked through is translucent. The faint glow indicates that some light is passing through the object, but its diffusion prevents a clear view of the torch.
