EM waves  

• Must travel through a vacuum
• Can travel through a medium or a vacuum
• Are the same type of wave as mechanical waves
• Can only travel through a vacuum

How are EM waves different from Mechanical waves?

• EM waves need a medium
• Mechanical waves need a medium
• EM waves can travel through empty space only
• Mechanical waves transfer matter

Which property determines the amount of energy for an ELECTROMAGNETIC wave?

• amplitude

• frequency

• particle size

• medium

What is a vacuum? 

• A space with only air in it
• A space with NO matter at all present
• A machine you use to do your chores

When the wavelength increases the frequency will

• increase
• decrease
