We have all seen that Cyclops projects a red-coloured beam out of his eyes. What is that red beam. Is it laser or something else?
The red beam coming out of Cyclops' eye isn't electromagnetic radiation, so there's no chance of it being LASER.
From official Marvel Universe wiki (See
Powers from left column):
Cyclops possesses the mutant ability to project a beam of heatless ruby-colored concussive force from his eyes, which act as inter-dimensional apertures between this universe and another.
