Answer:
alpha < beta < gamma.
Step-by-step explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
Generally, all radioactive elements are capable of emitting radiation. The three (3) types of nuclear radiation from least damaging to most damaging are; alpha, beta and gamma.
This ultimately implies that, alpha particles have the least damaging (penetrative) ability followed by beta particles and lastly, gamma rays.
