Wave particle also follows the theory of relativity

Speed of light is same for all observers. It doesnt
depend on motion of light source or server. Is this
theory is also same for all energy particles? I mean
to say Is this theory is also same for alpha rays?
However velocity of Alha particles is tenth part of
velocity of light.Is this theory is also same for
radio waves?

As far as we know, the speed of light is an upper limit for all
particles. Massless particles, such as photons (light, radio, gamma
rays,...), move at exactly the speed of light, while massive
particles, such as alpha particles, can move at any slower speed.

Only things without Rest Mass can travel at c. Things with mass like electrons, neutrons, protons, alpha rays, beta rays travel at less than c

Alpha Particles, No, their velocity transforms differently
Radiowaves yes, since they are travelling that the speed of light
