Blue and ultra-violet rays are the most energetic light. So why do red and infra-red light contain more heat energy? Continuing down the spectrum, do radio waves contain more heat energy than infra-red light?

1: If Proxima Centauri b had a Luna-sized moon, would it stop b from tidally locking to its sun? 2: If b's moon gave it a 24 hour or faster day, would b's magnetic field protect its atmosphere against being stripped away by solar flares? 3: Can it be determined how likely b is to have a large moon?
