are waves that are created as a result of vibrations between an electric field and a magnetic field.
radio waves
Ectromagnetic waves do not need medium while mechinal waves do need one. While electromagnetic waves travel in a vacuum while mechinal waves do not. While Electromagnetic Waves are considered as a disturbance. Machinal waves are considered as a periodic disturbance.
