Answer: Gamma rays
Step-by-step explanation:
Gamma rays have the most energies and shortest wavelengths on the electromagnetic spectrum. They are derived from free negatrons and stripped microscopic nuclei stimulated by powerful magnetic fields in exploding stars, colliding neutron stars, and supermassive black holes. Radio waves are the opposite. Radio waves have the lowest energies, longest wavelengths, and lowest frequencies of any EM radiation.
When the released energy reaches the outer layers of the ball of gas and dust, it moves off into space in the form of electromagnetic radiation. The ball, now a star, begins to shine.
