The doppler shift of light

  1. Oct 18, 2014 #1
    If an observer and a visible light source are in relative motion such that the visible light source is blueshifted to ultraviolet frequencies, then would this visible-light-turned-ultraviolet-light being received by the observer have the same properties as that of actual ultraviolet light i.e light that is ultraviolet in its inertial frame of reference? For example, could blueshifted light cause cancer like proper UV light?

    There is no difference between "proper UV light" and "other" (improper?) UV light.
    There is also no rest frame of light. Just a rest frame of the light emitter, but that does not matter.
