PLS HELP WILL FAN AND MEDAL!! what is the main difference between mechanical and electromagnetic waves. A:Mechanical waves Involve transfer of energy electromagnetic waves do not. B:Mechanical waves Require a medium to travel in electromagnetic waves do not. C:Mechanical waves Have Amplitude and wave length electromagnetic waves do not. D:Mechanical waves Have speed and Frequency electromagnetic waves do not.
hint: the electromagnetic waves are able to propagate in the empty space, please think about the solar energy which is able to reach the earth, well such energy is transported by means of electromagnetic waves. The sound waves, which are special mechanical waves, are able to propagate, for example, from a source, like a piano, to our ears, and such propagation is possible by means of vibration of the surrounding air between such piano, and our ears
