r (l) = [(n1-n0) / (n1 + n0)] 2 & time100% for gaas and air , then there is, r (l) = [(3.9-1) / (3.9 +1)] 2 & time100% = 35.02 this means that there are 35.02% of the photons will be reflected back to the gaas material, which reflected back chip, can not escape into the air, only 64.98 percent are likely to escape into the air. however, led light-emitting if a point when the full launch of its critical half-angle boundaries and the interface of two materials .menu board
