Question

wood is an example of an opaque object.
(A) True
(B) False

Answer 1

Hint: To find out whether the statement is true or false we should know about the terms transparent translucent and opaque which is the character of material based on the response it shows when light passes through it.

Complete step by step answer
Based on the response to the light the materials are classified into transparent translucent and opaque
Transparent: An object is said to be transparent if it allows light to pass through it. When light passes through the opaque object the light gets refracted and passes through the transparent object. When light passes through the transparent the speed of the light slows down.
Example: Glass, water, prism.
Translucent: An object is said to be translucent if that partially allows light to pass through it. When light passes through translucent objects. When light passes through the transparent objects it partially gets refracted and partially gets reflected by the object.
Example: Butter paper, thick glass, amber.
Opaque: An object is said to be opaque if it does not allow light to pass through it. When light passes through an opaque object either it gets absorbed in some cases or it gets reflected.
Example: Wood, mica, brick, leaf, metals.
Oil is a substance that exists as transparent, translucent and opaque sometimes according to their density.

Hence the correct answer is option is (A) True.

Note: Most of the materials are opaque in nature. There are only few materials that are transparent and translucent in nature. Only opaque and come translucent objects can have shadow when light does not pass through the object it creates the shadow.
