Question

State whether true or false.
Opaque objects allow light to pass through them.
(A) True
(B) False

Answer 1

Hint: The material which is clear and allows the light to pass through it is transparent. The material that is cloudy and only allows the part of the light to pass through is translucent. The material that does not allow the light to pass through is opaque.

Complete step by step answer:
Opaque are the objects which block the light traveling through it. Most of the light is either reflected by the opaque objects or absorbed by the opaque objects and converted to the thermal energy. Materials such as wall, iron materials, doors etc. are opaque to lights. The opaque objects are impenetrable to the lights, does not allow the light to pass through, does not transmit the radiation, does not transmit the sound and heat. The opaque objects do not allow the light to transmit because the light waves are reemitted from the surface of the opaque object. Opacity is also known as the reflection of the light without transmission.
The object which is opaque, then the colour of the object is seen clearly. For example, the paint is the material which has more opacity, so the colour of the paint is seen clearly. The black colour is the colour which has more opacity. So, the opaque objects do not allow the light to pass through them.
Hence, the option (B) is the correct answer.

Note: An opaque substance does not transmit the light, and therefore reflects, scatters, or absorbs all of the lights. Both the mirrors and the carbon black are opaque in nature. The white colour which hides the object below it and reflects back the light to the surface through the layers of colour.
