Question | Answer |
---|---|
waves | evidence of energy transfer through space. For this energy to be transferred, it has to start somewhere. The Disturbance is the place where energy transfer starts( a vibration) |
mechanical disturbance | the result of a movement.Grab a rope and move it |
elctromagnetic waves | produced form vibrations of electrically charged particles ( Protons/Electrons) within the electric field that surrounds them. |
medium | any matter (solid, liquid, gas) that has molecules to transport the wave’s energy. Think of the medium a the item that is disturbed with the vibrations. |
mechanical vs. electromagnetic waves | Mechanical Waves require a medium, but electromagnetic waves don’ t require a medium. |
