"Accelerating charge particle radiates electromagnetic waves"

When an electron jumps from lower energy level to higher energy level the electron gains energy and Jumping of electrons from higher energy level to lower energy level electrons releases energy in the form of radiation.

that radiation is in the form of electromagnetic waves.
