Question

Pick the object that only partially allows light to pass through it.

• A. Chocolate bar
• B. Glass bowl
• C. Pencil
• D. Butter paper

Answer 1

The correct option is D Butter paper

An object that allows only some light to pass through it, is called a translucent object. While the one that allows all the light to pass through, is a transparent object, and the object that blocks all the light or does not allow all the light to pass through, is an opaque object.

• Glass is usually a transparent object. So, it would allow all the light that falls on it to pass through.
• Pencils are made of wood which is an opaque substance. So, a pencil will block all the light that falls on it.
• A chocolate bar is also an opaque object. So, it wouldn't allow light to pass through it.
• Butter paper is a translucent object and therefore, it allows, not all, but some of the light falling onto it to pass through it.
