Question

Classify different objects depending on whether an object allows light to pass through it completely, partially or not at all.

Answer 1

Depending upon the amount of light passing through the object we can classify objects into the following three types:

1. Transparent objects. Those objects which allow light to pass through them completely.
2. Translucent objects. Those objects which allow only partial amount of light to pass through them.
3. Opaque objects. Those objects which do not allow light to pass through them at all.
