1. Red: even without knowing much, just by realizing that red is one of the extremes (think rainbow), we can assume that it is the longest. Also, infrared waves' wavelengths are longer than that of visible light.
2. Electromagnetic radiation: the fact that they have "ray" in the names shows that they are radiation. It's not ultraviolet because that is part of electromagnetic radiation.
3. Photon
