The use of which material can substitute for copper and reduce copper mine production?
gold
aluminum
quartz
glass

Glass

Explanation:

Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
