If you place a radiometer in a frictionless
enviroment and eliminate mechanical failure how
fast will it spin?
Since the frequency of c is very high, the
doppler shift of light reaching the white and
black side is virtually negilable, even if the
radiometer is spinning at high speeds,this also
applies to infrared radiation leaving the black
side.Therefore torque acting on the radiometer
doesn't decrease greatly with increasing speed
of the radiometer.Could the radiometer reach
high speeds? Which begs another question is the
the kenetic energy contained in the rotating
radiometer plus the the energy radiated from it
greater than the light energy radiated on to
the radiometer in the first place?
