Answer:
In 450 nanometre wavelength, colour produced by a LED using Gallium Indium Nitride is b) Blue.
Gallium Indium Nitride (GalnN) is a semiconductor used to make Light emitting diodes.
Other semiconductor includes - Silicon Carbide ( SiC) , Gallium Phosphide (GaP), Gallium Arsenide (GaAs) gives distinct wavelength of colour when all are mixed together at certain ratios.
Hence, the semiconductors used are responsible for the overall emission of particular wavelength of light.
