According to De Broglie equation a frequency is f=mc2/h. Is this only valid for particles in vacuum (c= speed of light in vacuum) or also in other medium? Should the speed of light "c" be replaced by the speed of EM waves in the required medium?

Is there any such thing as constant velocity if one consider the path of presumptive constant velocity to be part of a circle with infinitely large radius? Does it mean that acceleration exist no matter what due to a= w^2(-r) or v^2/(-r)?
