Your concept map will compare the manner in which energy is transferred by mechanical waves and electromagnetic waves. include the following somewhere in your concept map: • types of energy transferred • medium required (if applicable) for transfer of energy • speed of energy transfer through various mediums (solid, liquid, gas) mechanical waves transfer light energy can pass through matter

Mechanical waves

•types of energy transferred - mechanical energy

•medium required (if applicable) for transfer of energy - yes, mechanical waves require a transfer medium

•speed of energy transfer through various mediums (solid, liquid, gas) - speeds vary for mechanical waves through different mediums

Electromagnetic waves

•types of energy transferred - electromagnetic energy

•medium required (if applicable) for transfer of energy - no medium required

•speed of energy transfer through various mediums (solid, liquid, gas) - transfer speed varies for electromagnetic waves through different mediums

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess
