When candle is burnt then its wax which is a having chemical potential energy in it will burn and convert its chemical potential energy into light energy and thermal energy. So here the wax will melt down after burning and few of its part will evaporate and convert its energy into thermal energy and light energy both. With radiation, a heat source does not have to touch the object being heated; radiation can transfer heat even through the vacuum of space.
