Question
sir please tell me the difference and similarities between radio signals(waves) and light waves
Radio waves are a form of electromagnetic waves, just like light waves. By light waves, I'll assume you mean visible electromagnetic waves. The only thing that separates them is that radio waves have much longer wavelengths. Physically they are otherwise identical types of waves. Electromagnetic waves interact with matter on a length scale close to their wavelengths, which is why we don't see radio waves but something big like a car antenna can pick them up.

Expertise
Fusion, solar flares, cosmic rays, radiation in space, and stellar physics questions. Generally, nuclear-related astrophysics, but I can usually point you in the right direction if it's not nuclear-related or if it's nuclear but not astrophysics.
Experience
Currently a physics professor at the University of Texas of the Permian Basin. Doctoral dissertation was on a reaction in CNO-cycle fusion, worked in gamma-ray astronomy in the space science division of the naval research laboratory in the high-energy space environment branch.
