Question

Does area opaca transmit light ??if yes what does it mean ??

Answer 1

I'll assume you mean 'opaque area', and then answer. No it doesn't transmit any light.

Answer 2

Answer:

Transmission of light is the moving of electromagnetic waves (whether visible light, radio waves, ultraviolet, etc.) through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
