Question

(iii) An oily thin paper sheet will be
(a) transparent
(b) translucent
(c) opaque
(d) cannot be predicted

Answer 1

The correct answer is Option (b) translucent.

• An oily thin paper sheet will be translucent.

• Transparent material allows light to move through it. An example is window glass.
• Translucent material partially allows light to move through it. An example is butter paper or oily thin paper.

• Opaque material completely obstructs the light to move through it. An example is A4 size paper or wall.

Answer 2

Option (b) translucent is the correct answer.

An oily thin paper sheet will be translucent.

Explanation:

• Translucent objects are those which permit the passage of light.
• When light strikes translucent materials, the incident light  changes the direction multiple times and gets scattered as it passes through.
• Here one cannot see clearly through the paper.
• Objects is  unclear on the other side of a translucent object.
• Examples of translucent material are Plastic and frosted glass.
• Translucent objects will allow some part of the light to travel through the objects.

• When an object is translucent, it will allow more light to pass through and the reflecting off the objects behind the surface will  allow them to reflect their own color wavelengths and start increasing their visibility.
