![]() Opaque and translucent glasses have great applications in real life.Pale skin in humans is translucent which is why you can see the blue or green veins present in the human body through the skin. As a matter of fact, humans have translucency, to some extent. Surprisingly, animals are not just the only example of one of the three phenomenons under discussion.The best example, in this case, is of Jellyfish. Some marine animals are also nearly transparent because their transparency allows them to protect themselves from predators.The electromagnetic waves that travel through them are of specific frequencies and they can travel through the optical fibres with minimal dissipation of energy. Optical fibres utilize the phenomenon of total internal reflection of light to work.Optical fibers, which are very commonly used in communication, have a transparent cladding and core.This behavior results in a quick attenuation of the incident light rays, and, therefore, makes the said substance opaque to radiation. As a result, whenever light rays pass through or encounter a metallic object, those free electrons in the metal absorb the light rays and re-emit them frequently. ![]()
