The correct option is C Muslin cloth
Type of objects:
The objects are classified based on how much amount of light they transmit through them. Mainly there are three categories as transparent objects, opaque objects, and translucent objects.
- Transparent objects: These objects allow all light rays to pass through them, such as glass window pane, clear water, and glass light bulbs.
- Opaque objects: These materials are opposite to transparent materials. They do not allow light rays to pass through them, like wood and stone.
- Translucent objects: These objects partially allow light rays to pass through them. Examples: frosted glass and plastic paper. When we see through translucent objects, we can get an idea of the presence of images or materials on the other side of the surface but a clear image will not be obtained.
Explanation for the correct option:
As muslin cloth partially allows light to pass through it, hence this is a translucent material. So Paheli should pick Muslin cloth.
Hence, option (C) is correct.
Explanation for incorrect options
Option A: The Glass tumbler is a clear object that gives a clear picture of objects on another side, hence is a transparent object.
Option B: The mirror reflects all rays falling on it, we can see our own image but we can't see objects that are behind the mirror, hence mirror is an opaque object.
Option D: Aluminium foil does not allow light rays to pass through, hence this is an opaque object.
Hence, options (A), (B), and (D) are incorrect.
