Question: GaAs and GaP (Eg = 2.26 eV) make solid solutions that have the same crystal structure as the parent materials, with As and P randomly

GaAs and GaP (Eg = 2.26 eV) make solid solutions that have the same crystal structure as the parent materials, with As and P randomly distributed throughout the crystal. GaPxAs1 -x exists for any value of x. If we assume that the band gap varies linearly with composition between x = 0 and x = 1, estimate the band gap for GaP0.5As0.5. What wavelength of light does this correspond to?
