All electromagnetic radiation travels at the same velocity.
Radiowaves are longer in wavelength than microwaves (which are longer than the wavelengths of visible light), but all of these, and even UV and X-Rays (which have very short wavelengths) travel at the same speed through a vacuum (and very close through air).

Both are forms of electromagnetic radiation, all of which travel at the speed of light (~3 x 10^8 meters/sec).
The difference between the two is the frequency (and thus the corresponding wavelength), not their speed or velocity.

a microwave because the faster the speed of radiation the more heat is produced

Microwave radiation is faster than radio wave radiation. Radio waves have a longer wavelength on the light spectrum
