" B) A thick waterproof coating of "

A thick waterproof coating of …………..occurs over the epidermis in desert plants.

To produce a minimum reflection of wavelength near the middle of visible spectrum (550 nm), how thick should a coating of MgF_(2) (mu = 1.38) be vaccum-coated on a glass surface?

In one process of waterproofing, a fabric is expsoed to (CH_(3))_(2) SiCl vapour. The vapour reacts with (OH) groups on the surface of the fabric or with traces of H_(2) O to form waterproofing film of by the reaction Where n is large integer. The waterproofing film is deposited on the fabric layer upon layer. Each layer is 10 Å thich [the thickness of the (CH_(3))_(2) SiO group]. How much (CH_(3))_(2) SiCl_(2) is required to waterproof one side of a piece of a fabric, 1.0 m by 3.0 m , with a film 1000 layers thick? The density of the film is 1.0 g cm^(-3) . (Atomic weight of Si = 28 and Cl = 35.5 )
