What are the differences between bremsstrahlung and characteristic radiation in terms of their generation and properties?

Bremsstrahlung radiation is produced when a charged particle is decelerated, emitting a continuous spectrum of X-rays. Characteristic radiation, on the other hand, is generated when an electron transitions to a lower energy level, emitting X-rays at specific energies unique to the material. Bremsstrahlung radiation has a continuous spectrum, while characteristic radiation has distinct peaks at specific energies.
