Question

A medium which partially allows light rays to pass through it is
A) Transparent
B) Opaque
C) Non - luminous
D) Translucent

Answer 1

Hint: You need to know the meaning of all the terms in the option.

Complete step by step solution:
A medium that allows all the light incident on it to pass through it is called a transparent medium.

A medium that does not allow light to pass through it is called an opaque medium.

Objects that do not emit light on their own are called non–luminous objects.

Objects that allow only a part of the light incident on them to pass through it are called translucent media.

In short,
1)Opaque objects do not allow light to pass through them.
2)Transparent objects allow light to pass through them and we can see through these objects clearly.
3)Translucent objects allow light to pass through them partially.

Correct answer: D) Translucent

Note: Examples of translucent media are a shower stall, smoked glass, sun glasses and butter paper. Light travels in a straight line, and its rays represent the path of light.
