A charge oscillates. It creates a changing electric field, which induces changing magnetic field which in turn induces changing electric field, and so on. This whole phenomenon spreads out in space and that is called as 'Electromagnetic radiations'. So, you see, the radiations themselvesdo not oscillate.
