Question

Regina is making observations of waves from different sources. She wants to classify the waves as either mechanical or electromagnetic. Which question will BEST help Regina to classify the waves?

A.
Can the wave transfer matter?


B.
Can the wave transfer energy?


C.
Can the wave travel through a vacuum?


D.
Can the wave travel through a liquid?

Answer 1

A. Can the wave transfer matter?

Step-by-step explanation:

• EMW is made by vibrations of the charged particles and they work on a mechanical waveform. The energy is transferred through a vacuum and thus they need a medium to pass the energy.

• Thus in order to transport the energy from one place to another, such as a sound wave. Hence first she should have knowledge about the chemical and physical properties of the waves such as can they transfer matter.
