50% energy
Quasar actually means quasi-stellar radio sources so we thought that it was giving off radio waves but we did not put into account the redshift that causes the stretching of the wavelength meaning that it most likely gives off microwaves.
Because, it is booming hot.
Light, heat, radiation, x-rays, gamma rays; any of these answers would be correct.
Infrared light doesn't "give off" energy; in this case, it IS the energy.
you give off calary and diet energy
Yes the sun does give off solar energy. It also gives off heat and light energy.
No. Neither High or Low pressure Sodium Vapour lamps give off much energy in the UV wavelengths.
Computers give off mostly heat, but also give off magnetism in the form of radio waves. Plus their displays give off light energy and the speakers give off sound waves. The fans inside create kinetic energy.
When electrons fall to a lower energy level, they give off energy in the form of light.
give off heat
Radiation of lightning, X-ray, can have energy exceeding 20MeV.
