ASAP please

3. Using Vegard's law, balance the lattice parameter of quaternary alloy Gas-xInxAs to that of GaAs which is used as the substrate material. This ternary alloy is achieved by adding appropriate portion of GaAs to InAs is used for optoelectronic devices. Discuss the criteria for lattice matching via Vegard's law, how well it represents the actual lattice parameters of the alloys (experimental values)
