What is a non dispersive medium?

Assertion (A): Sunlight reaches us without dispersion in the form of white light and not as its components. Reason (R): Dispersion takes place due to variation of refractive index for different wavelength but in vacuum the speed of light is independent of wavelength and hence vacuum is a non dispersive medium.
