Polycarbonate materials used for applications such as safety glasses are optically transparent because:.A) The molecular weight of the polymer chain is kept to a narrow range. B) The lack of metallic bonds in the molecular chain ensure the material will transmit light. C) The spherulite radius is maintained at a very large value that is much higher than the wavelength of optical light so the material is transparent. D) Crystallization is avoided and the material is kept in the amorphous state.
