White light is a mixture of all colours, and each colour has a different wavelenght. So, either by using the diffraction grating formula, or descriptive knowledge of diffraction, the longer wavelength red light is diffracted through a greater angle than the shorter wavelength blue/violet light. So you see spectra.
