Mechanical vs Electromagnetic

Which is true of a mechanical wave?

• It must have a medium

• It must travel in empty space.

• It can travel in a vacuum.

• Both sound and light are examples.

Waves are categorized by:
*whether or not they require a medium to move through (EM vs mechanical) OR
*how the particles move in relation to the movement of the wave (transverse vs longitudinal).
A wave that requires a medium to move through is called a
(NOTE: Take time to study the chart before answering.)

• longitudinal wave

• transverse wave

• electromagnetic wave

• mechanical wave

A microwave is an example of what type of wave?

• electromagnetic wave

• mechanical wave
