Active passive :3 Lopyou all.

c. When the glass surfaced are shaped appropriately and polished to a smooth finish, they (coat) ___ with whatever reflective material the designer has chosen. Regardless of the coating material, it (apply) in apparatus called an evaporator. The method of coating (create) ___ very uniform and highly reflective surfaces.

d. Several evaporations steps then (combine) ____ to make multiple layer coating. Clear dielectric materials may be evaporated on top of metal or other dielectrics to change the reflective or mechanical properties of a surface. Mirrors with silvering on the back, of the glass, for instance, often (have) ____ an opaque dielectric layer applied to improve the reflectivity and keep the metal from scratching. One way mirrors (be) the exception to this procedure, in which case great care must be taken not to damage the thin metal coating.

e. Finally, when the proper coatings have been applied, the finished mirror (mount) ____ in a base or packed carefully in a shock resistant package for shipping.
